Aviation titanium alloy parts forging

July 4, 2023/in company news /by 合金

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.

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).

June 25, 2023/in company news /by 合金

When I tell the production process and steps of making stainless steel seamless pipe, I inform in advance that the production process of stainless steel seamless pipe is different, and the corresponding production process is also different. For example, stainless steel seamless pipe has a division of cold-rolled pipe and hot-rolled pipe, for size requirements and high-quality requirements of stainless steel sanitary seamless pipe, one must use the production process of cold-rolled, cold-drawn, or a combination of both.

Stainless steel seamless tube production steps:

1, the choice of high-quality up to standard 304, 316L stainless steel raw material pipe billet by hollowing, head, annealing, and other operations.

2, after the completion of the above operations followed by multiple cold drawing (cold rolling) processes, the cold rolling of the pipe in the multi-roller mill, stainless steel pipe in the variable section of the circular hole groove, and immovable conical top head composed of ring-shaped hole type rolling.

3, after cold-rolled stainless steel tube will have a large yield strength coefficient, not suitable for flaring, bending, and other phenomena, in order to achieve stainless steel pipe sanitary standards, cold-rolled tubes also need to be bright annealing, demagnetization, pickling, straightening, and other steps.

5, stainless steel pipe pickling process, fittings in the pickling passivation at the same time can remove the surface of the workpiece oil, rust spots, weld spots, oxide layer, free iron, and other dirt, the surface becomes uniformly silvery white after treatment while preventing the metal from over corrosion and hydrogen embrittlement phenomenon, inhibit the generation of acid mist.

6, stainless steel pipe after the above process, the next is the polishing process, the inner wall of the pipe, the outer wall polishing mesh standard of 400 mesh, polishing treatment of the tube inside and outside the surface finish can reach the mirror standard (also known as sanitary standards).

7, polished stainless steel pipe needs to go through the metal flaw detection machine (or hydraulic test) for internal flaw detection and strict hand selection of steel pipe quality inspectors, qualified products can be packaged for delivery.

The production process of making stainless steel seamless pipe.

Production process: 1, steel making → 2, rolling round steel (skinning) → 3, perforation (annealing) → 4, cold drawing → 5, cold rolling (annealing, demagnetization, pickling, cleaning) → 6, inner wall polishing (400 mesh) → 7, outer wall polishing (400 mesh) → 8, air pressure testing → 9, surface testing → 10, paste trademark and certificate of conformity → 11, packaging → 12, factory

Stainless steel contains a certain amount of chrome alloy elements, which can form a strong oxidized film on the surface of the steel that is insoluble in some media so that the metal is isolated from the external medium without chemical action. Therefore, it is less prone to rust than other steel grades, so the choice of alloying element composition is crucial.

Monel400 chemical element composition:
C: ≤0.3

Si: ≤0.50

Mn: ≤2.0

Ni: ≥63

Cu: 28 to 34

S: ≤ 0.024

Heat treatment methods and features:
1 Solid solution strengthening is an important form of metal strengthening, which increases the strength and hardness of metals by forming solid solutions. When the solute content is appropriate, the strength and hardness of the material can be significantly improved, while the plasticity and toughness are not significantly reduced.

2 Aging enhancement is divided into artificial aging and natural aging. Natural aging strengthening is to strengthen the alloy during room temperature placement; artificial aging strengthening is to strengthen the alloy during low-temperature heating. Both are based

3 Precipitation strengthening is premised>

4 Grain boundary strengthening occurs because the grain boundary of the alloy is weak at high temperatures, and the addition of trace amounts of boron, zirconium, and rare earth elements can improve the grain boundary strength.

Application of duplex stainless steel in the field of environmental protection

June 8, 2023/in company news /by 合金

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. In the pharmaceutical enterprise industry organic waste gas treatment system, its pneumatic switching valve body is made of 2205 duplex stainless steel. Due to the requirements of the environment, ships, especially chemical ships’ flue gas desulfurization emission absorption towers also have a large number of 2205, 2507 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.
