Why Inconel 600 is popular in high temperature and corrosion resistant valve?

Nickel-based alloy Inconel is widely used in the production of high temperature and corrosion-resistant valves. As specified in ASTM UNS N06600, the specified Inconel 600 is specified in ASTM A494 CY‐40. They are mainly used in stress corrosion resistant environments, especially for high concentration chloride media, when the Ni content is greater than 45%, it […]

Classification of corrosion-resisting nickel-based alloys

Alloys with nickel above 50% are known as nickel-based corrosion-resistant alloys. Like Austenitic stainless steel, the microstructure of nickel-based alloys is single-phase austenitic without phase change in solid-state, and the grains of base metal and weld metal cannot be refined by heat treatment. It has excellent corrosion resistance and high-temperature resistance performance that can withstand […]

A complete introduction of Hastelloy B,C,G alloy for chemical industrial

Ultra-low carbon Ni-Cr-Mo alloy is known as Hastelloy alloy. Hastelloy is a trademark of Haynes International company, consist of the letter “HA” in Haynes, “STELL” in STEILITE and “OY” in ALLOYS. As an advanced nickel-based alloy, Hastelloy offers excellent corrosion resistance to a variety of harsh corrosion environments such as wet oxygen, sulfurous acid, strong […]

What’s the Power Metallurgy High Speed Steel?

Powder high-speed steel is a kind of metallurgical steel, which is made from molten steel by high-pressure atomization, through screening, compaction, vacuum sealing and hot-static pressing, and then forged and rolled. Powder metallurgical steel is compacted by uniform and fine carbide particles. It overcomes a series of shortcomings caused by carbide segregation and forms a […]

A brief introduction of mold steel

Last article, we have introduced the “Tool Steel Grades Definition System”. As we all know, tool steels can be classified to many different types according to different standards. According to their detail application, tool steels can be divided into cutting tool steels, mold steels and gauge steels. Here we introduce the classification of mold steel. […]

The welding of duplex stainless steel S32750

Compared with Austenitic stainless steel, super duplex stainless steel has more Cr and Mo contents, which is beneficial to form ferrite and improve the corrosion resistance of the steel. The addition of Ni, N, Cu and Cu can improve the corrosion resistance of steel to non-oxidizing medium. Super duplex stainless steel has good weldability without welding hot and cold […]

What’s the effect of Co for carbide alloys?

Cobalt (Co) is a magnetic and scarce metal element. Cobalt resources are widely but imbalanced in the world. The reserves of Congo (DRC), Australia and Cuba account for 70% of the total global reserves, of which Congo accounts for 47.89%. Cobalt resources are mostly associated with copper-cobalt ore, nickel-cobalt ore, arsenic-cobalt ore and pyrite deposits. […]

What’ s metal cladding plate?

Metal cladding plate is composed of base steel (plain carbon steel) and composite layer (corrosion resistant metal) through the explosion and rolling process. The base material can be ASTM A 516 Gr70, ASTM A36, ASTM A283, ASTM A387 and other ordinary carbon steel and special steel. The cladding material can be ordinary stainless steel such […]

How to make titanium alloy easy to machine?

As everyone knows, Titanium and its alloys are difficult to machine and process due to their high strength, low thermal conductivity and chemical reactivity with tool materials (at elevated temperatures), pose a hazard to the tool and significantly reduce the tool life. In addition, a relatively low Young’s modulus leads to spring-back and chatter leading […]
