Characteristics of INCONEL alloy C276

What are the properties of INCONEL alloy C276?

Nickel alloys need to work hard in extreme environments containing corrosive acids and other aggressive media. Even under the harshest conditions, INCONEL alloy C-276 is a popular choice. Here, we look at its properties and why they are suitable for these harsh environments.

There are many factors to consider when choosing the right material for harsh industrial environments. You need to know what kind of corrosive media will be present, what the operating temperature range is, and what loads the material will be subjected to. In a harsh situation, the material will need to be able to operate in some of the most corrosive conditions on earth, at high temperatures and high pressures.

Finding an alloy that can survive in such extreme environments is not an easy task. INCONEL C-276 alloy is a material worth considering due to its excellent corrosion resistance to a wide range of aggressive media. It is widely used in a variety of different industrial applications and is considered to be one of the most versatile options available in harsh environments. As a supplier of nickel alloys, Shanghai Makan Alloys has a comprehensive understanding of each material and a wealth of experience in the properties, characteristics, and applications of this technologically leading alloy.INCONEL alloy C276 suppliers

1. Alloy C276 Main Characteristics
INCONEL Alloy C-276 is used in harsh environments due to its nickel alloy properties. It is a nickel-chromium superalloy with a high molybdenum content (15-17%). It is also possible to control the tungsten and iron content and to strictly limit the carbon content. The low carbon content minimizes carbide precipitation during heat treatment and welding. This means that the alloy retains its excellent resistance to pitting and crevice corrosion when used in welded structures. In other materials, the weld zone is weakened by heat during the welding process and is, therefore more resistant to corrosion.INCONEL alloy C-276 is sometimes covered with lower alloyed materials in the weld zone to provide additional protection and even higher performance in industrial applications.

The material’s corrosion resistance is one of its main highlights. Even in very harsh environments, it resists general corrosion such as stress corrosion cracking, pitting, and crevice corrosion very well. It is also extremely resistant to sulfuric, hydrochloric, and phosphoric acids. Highly oxidizing, neutral, and acidic chlorides; as well as solvents, formic and acetic acid, acetic anhydride, wet chlorine gas, hypochlorite, and chlorine solutions. This is what makes it so well used in the chemical processing industry. Finally, it also has excellent resistance to seawater corrosion, especially in crevice conditions.

2. Alloy C276 industry applications

With such a wide range of resistance, it is no wonder that INCONEL alloy C-276 is used in many industrial applications.

For example, it is used in flue gas desulfurization (FGD) systems to control air pollution in power plants. Components it is used in include scrubbers, piping, and stack liners. Compared to other alloys, INCONEL C-276 alloy has the ability to withstand higher chloride content before localized corrosion occurs. Given the presence of chlorides in scrubber liquids and gas condensates, this is certainly the preferred choice in this industry.

This nickel alloy has also been chosen for certain oilfield and subsea applications. When recovering and processing sour natural gas, which often contains hydrogen sulfide, carbon dioxide, and chlorides, the material needs to have good resistance to sulfide stress cracking and stress corrosion cracking. INCONEL alloy C-276 has high levels of nickel, chromium, and molybdenum, which together can provide this resistance even at high temperatures in deep wells. It’s used in things like piping, downhole, and surface components.

Its composition is also used for pollution control and waste treatment in very harsh environments. The high molybdenum content of INCONEL alloy C-276 helps create resistance to pitting and crevice corrosion. It is used in the most aggressive portions of waste liquid handling systems where other materials will not be able to cope with harsh conditions. In air pollution control, the alloy is used in stack linings, ducts, dampers, scrubber towers, stack gas reheaters, fans, and fan shrouds.

INCONEL alloy C-276 is also an important material in chemical processing. It has been selected for use in processes containing ferric and copper chloride ions, chlorine, hypochlorite, chlorine dioxide, organic acids, acetic anhydride, seawater, brine, and acidic oil and gas wellhead fluids. It is used in heat exchangers, reaction vessels, evaporators, and transportation piping.

Aviation titanium alloy parts forging

Aviation titanium alloy parts forging

Titanium is an important structural metal developed in the 1950s, and titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, research, and development of its successive and practical applications.

In the 1950s to 1960s, the main development of high-temperature titanium alloys for aircraft engines and structural titanium alloys for airframes, the 1970s to develop a number of corrosion-resistant titanium alloys, and since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural parts for rockets, missiles, and high-speed aircraft.

Titanium is an isomer with a melting point of 1668°C. Below 882°C, it has a dense hexagonal lattice structure, called α-titanium; above 882°C, it has a body-centered cubic lattice structure, called β-titanium. Using the above two structural characteristics of titanium, add the appropriate alloying elements so that its phase change temperature and phase content gradually change and get different organizations of titanium alloys (titanium alloys). At room temperature, titanium alloys have three kinds of matrix organization, and titanium alloys are divided into the following three categories: α alloy, (α + β) alloy, and β alloy. In China, they are expressed as TA, TC, and TB respectively.

Aviation titanium alloy parts forging

Alpha titanium alloy is a single-phase alloy composed of α-phase solid solution, whether at general temperature or at higher actual application temperature, it is α-phase, with stable organization, higher wear resistance than pure titanium, and strong oxidation resistance. In the temperature of 500 ~ 600 ℃, it still, maintains its strength and creep resistance, but can not be heat treated to strengthen, room temperature strength is not high.

β titanium alloy is a single-phase alloy composed of β-phase solid solution, titanium alloy without heat treatment has high strength, and quenching, the aging alloy is further strengthened, with room temperature strength up to 1372 ~ 1666 MPa; but the thermal stability is poor, not suitable for use at high temperatures.

α + β titanium alloy is a duplex alloy with good overall performance, good organizational stability, good toughness, plasticity, and high-temperature deformation properties, can be better for hot pressure processing, quenching, and aging to strengthen the alloy. The strength after heat treatment is about 50% to 100% higher than the annealed state; high-temperature strength, can work at a temperature of 400 ~ 500 ℃ for a long time, and its thermal stability is second to alpha titanium alloy.

The most common of the three titanium alloys is α titanium alloy and α + β titanium alloy; α titanium alloy has the best machinability, α + β titanium alloy is the second, β titanium alloy is the worst. α titanium alloy code TA, β titanium alloy code TB, α + β titanium alloy code TC.

Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys, and special functional alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys). The composition and properties of typical alloys are shown in the table.

Heat-treated titanium alloys can have different phase compositions and organizations by adjusting the heat treatment process. It is generally believed that the fine equiaxial organization has better plasticity, thermal stability, and fatigue strength; the needle-like organization has higher endurance strength, creep strength, and fracture toughness; the mixed equiaxial and needle-like organization has better overall performance.

Titanium alloys have high strength and low density, good mechanical properties, good toughness, and corrosion resistance. In addition, the titanium alloy process performance is poor, and cutting and machining difficulties, in hot processing, very easy to absorb impurities such as hydrogen, oxygen, nitrogen, and carbon. There are also poor anti-wear properties, the production process is complex. The industrial production of titanium was started in 1948. The need for the development of the aviation industry, the titanium industry to an average annual growth rate of about 8%. The annual output of titanium alloy processing material in the world has reached more than 40,000 tons, and there are nearly 30 kinds of titanium alloy de grades. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5) Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).

welding steel pipe process

2, adjust the opening of the welding bevel based on the wall thickness of the steel pipe itself, if the wall thickness is thicker then you can open it a little larger, and if it is thinner then you can properly small, it be able to adjust according to the actual situation. If you feel that the bevel opening is a bit large, you can properly leave a small gap on the counterpart, usually about 1-1.5 times the diameter of the welding rod or wire, depending on the steel pipe.

3, welding treatment of steel pipe welding is currently recommended to use half and half of the form of better, do not be too eager to pay attention to the meticulous and rigorous, to be able to weld the steel pipe in place. If the wall of the steel pipe is thicker, then you can choose the layered treatment, which can also have a more secure effect. Handling steel pipe welding to have a grasp of all aspects of the matter, in strict accordance with the step requirements, relatively speaking, is able to reduce the risk of problems, to protect the smoothness of steel pipe welding.

Application of duplex stainless steel in the field of environmental protection

With the development of the economy and society, the industrial production process and people’s lives produce more and more “three wastes” (waste gas, waste water, waste residue) that are threatening people’s homes to survive. The “three wastes” for recycling, purification treatment, or comprehensive use, to achieve standard discharge, to prevent environmental pollution, and waste into treasure, for the benefit of mankind. Duplex stainless steel, because of its unique physical and chemical properties, is one of the materials of choice for the manufacture of “three wastes” recycling and purification equipment and facilities.

Duplex stainless steel has the advantages of both ferritic and austenitic stainless steel, with good corrosion resistance, mechanical properties, and welding properties. Due to its excellent overall performance and manufacturing technology breakthroughs, in recent years has been used in large quantities for the manufacture of equipment under the conditions of chloride and hydrogen sulfide media, especially suitable for the manufacture of heat exchangers containing chloride-ionized water or brackish water cooling media, but also for the manufacture of dilute sulfuric acid solutions and storage and transportation of pure organic acid equipment. In place of 304 stainless steel in heavily loaded structural materials, it also improves the service life of the equipment and reduces material costs. In recent years, due to the development of industrial level and increasingly high requirements for environmental protection, duplex stainless steel in the field of environmental protection has also been widely used, especially in industrial waste gas, wastewater, and solid waste treatment is widely promoted.

Exhaust gas treatment

Exhaust gas pollution is one of the biggest environmental problems facing mankind, such as coal-fired boilers in power plants, gas furnaces in fertilizer plants, and coke ovens in iron and steel plants contain a large number of harmful gases and toxic dust particles such as sulfide, nitrides, chlorides, fluorides, etc., which need to be removed before discharge into the atmosphere, the most common method is to pass the exhaust gas through the absorption tower equipped with lime slurry or limestone The most common method is to neutralize the waste gas by passing it through an absorption tower with lime slurry or limestone, which generates corrosive gases containing HCl and HF, causing severe corrosion to the absorption tower. Therefore, in order to ensure the continuous operation of the system, it is necessary to use good corrosion resistance of stainless steel, and 2205, and 2507 duplex stainless steel has the advantages of this, so in the flue gas treatment absorption tower device is used in large quantities.

Statistics show that in recent years in Europe to build a number of sets of flue gas desulfurization devices are used in a large number of duplex stainless steel manufacturing. Canada Coleson Cove power plant is the first in North America at the top of the absorption tower using 360 tons of 2205 duplex stainless steel. In recent years, domestic industrial flue gas treatment equipment also began to use duplex stainless steel materials, such as Huadian International Zouxian Power Plant Phase III flue gas desulfurization absorption tower also uses a large number of 2205, 2507 duplex stainless steel as a manufacturing material. At the same time in the flue gas dust treatment system, the wet type electric dedusting technology (WESP) device system dust collection plate, anode plate, and cathode line using 2205 duplex stainless steel manufacturing.

Wastewater treatment

With the construction of cities and towns and industrial processes at home and abroad, the discharge of wastewater has become the culprit affecting the deterioration of global water resources and needs to be treated harmlessly before it can be discharged. Municipal sewage, hospital sewage, livestock breeding sewage, etc. contain a large number of Cl- ions, phosphorus compounds, nitrogen compounds, organic compounds, etc., especially the content of these ions or compounds in the sludge is higher. The content of various metal ions, Cl- ions, phosphorus compounds, nitrogen compounds, organic compounds, etc. in industrial wastewater is also high. If these ions or compounds are discharged without treatment, they will cause significant pollution to the water environment and pose a major threat to human life.

As some of the equipment or piping systems in the sewage treatment system are permanently built, and urban and industrial sewage, sludge is corrosive, such as improper selection of materials not only to sewage treatment equipment, piping systems cause serious corrosion, sewage treatment equipment or piping systems maintenance difficulties, sewage treatment companies will also cause significant economic losses. So sewage treatment equipment and piping systems need to choose corrosion-resistant materials manufacturing.

Wastewater treatment equipment and piping systems are generally made of 304 stainless steel, but the sewage Cl- greater than 200ppm, wastewater, and sewage treatment equipment or piping systems are best used 2205 duplex stainless steel or better corrosion resistance 2507 super duplex stainless steel manufacturing, such as stainless steel pickling plant, auto parts plating plant, pulp or paper mills, mines, coal chemical industry, chemical fertilizer plant, the phosphate fertilizer plant, sugar plant, brewery and other industrial waste liquids, sewage treatment systems or equipment are manufactured using 2205, 2507 duplex stainless steel materials.

Waste treatment

The same as sewage treatment and waste fume treatment, duplex stainless steel in the solid waste treatment process is also used in large quantities, this is because the solid waste contains a large number of metal ions, a variety of complex organic substances, chlorides, fluoride, sulfides, etc., these substances are not only toxic but also acidic and alkaline, in the treatment process of serious corrosion of equipment. Solid waste treatment systems with strong corrosive properties of solid waste contact parts, and piping systems need to use duplex stainless steel material manufacturing.

Toxic, acidic, and alkaline chemical, petroleum, pharmaceutical, and other solid waste combustion process, the need for its harmless treatment, solid waste treatment system configuration of the scrubber tower, and wet electrostatic equipment are manufactured using 2205, 2507 duplex stainless steel. In the electroplating solid waste or other solid waste containing rare metals such as gold, silver, cobalt, etc., the use of mixing equipment, piping, and electrolytic purification equipment is used in a large number of 2205, 2507 duplex stainless steel manufacturing. In the Metallurgical manufacturing industry, such as carbon steel, stainless steel pickling solid waste treatment of mixing equipment, ball making equipment local parts also have used 2205 duplex stainless steel.

In summary, because of the excellent mechanical properties of duplex stainless steel, wear resistance, stress corrosion, chloride ion corrosion, and resistance to uniform corrosion performance and other comprehensive excellent performance, its application in the field of environmental protection is becoming more and more widespread.

Share the performance of stainless steel plate

Hello everyone, today I would like to share with you the properties of stainless steel sheets. A stainless steel sheet is a widely used metal material with good corrosion resistance, strength, and workability. It is widely used in manufacturing, construction, chemical industry, and other fields.

First, the corrosion resistance of stainless steel sheets is excellent. This is because there is a dense chromium oxide layer on the surface of stainless steel sheets, which can effectively prevent oxidation, corrosion, and wear, thus keeping the appearance and performance of stainless steel sheets unchanged for a long time. In addition, the corrosion resistance of stainless steel sheets is also affected by their alloy composition and manufacturing process.

Secondly, stainless steel plate has high strength and hardness. The strength and hardness of this material can be adjusted according to the needs of the application, so stainless steel plate is widely used in manufacturing and construction. In addition, stainless steel sheet also has good workability and can be stamped, bent, sheared, and other processing according to the need to adapt to a variety of different applications.

Finally, the performance of stainless steel sheets is also affected by their surface treatment and surface quality. Surface treatment can change the color, texture, and luster of the stainless steel plate, making it more beautiful and durable. Surface quality includes indicators such as surface flatness, surface finish, and surface defects, which directly affect the service life and performance of stainless steel sheets.

In short, stainless steel sheet is a metal material with excellent performance, good corrosion resistance, strength, and workability. Stainless steel sheet performance is widely used in manufacturing, construction, chemical industry, and other fields, providing strong support for the development of various industries.
