Hastelloy C22

Hastelloy C22 is an alloy made up of nickel, chromium and molybdenum. It offers superior resistance to oxidizing media like chloride solutions, strong acids and seawater. Its abrasion and corrosion resistance make it ideal for industrial applications such as petrochemical processing equipment, pump valves, heat exchangers and nuclear components. Furthermore, this alloy provides excellent weldability and mechanical strength at elevated temperatures. With its exceptional durability, Hastelloy C22 is the perfect choice for any application requiring robust metal products that can stand the test of time!


Hastelloy C22 is a nickel-chromium-molybdenum alloy with excellent corrosion resistance in oxidizing and reducing environments. This alloy is especially valuable in chemical processing due to its resistance to strong organic and inorganic acids, chlorides, dry chlorine, chloride solutions and many other corrosive media. It is also highly resistant to pitting, crevice corrosion, intergranular attack and stress corrosion cracking. The tensile strength of Hastelloy C22 can range up to 80ksi (550MPa) with good flexibility for fabrication purposes. Due to its superior properties, this material finds use in various industries, including marine engineering, power plants, chemical processing plants, etc.
