Hastelloy C22 Plate

HASTELLOY C-22 alloy (UNS N06022) is one of the well-known and well-proven nickel-chromium-molybdenum materials, the chief attributes of which are resistance to both oxidizing and non-oxidizing chemicals, and protection from pitting, crevice attack, and stress corrosion cracking. Its high chromium content provides much higher resistance to oxidizing media than the family standard, C-276 alloy, and imparts exceptional resistance to chloride-induced pitting, an insidious and unpredictable form of attack, to which the stainless steels are prone.

Hastelloy C-22 Characteristic

• Nickel-Chromium-Molybdenum-Tungsten alloy with better overall corrosion resistance compared to any other Ni-Cr-Mo alloys,such as Hastelloy C-276,C-4 and alloy 625.
• Good resistance to pitting corrosion,crevice corrosion and stress corrosion cracking.
• Excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
• Offering optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams.
• Can be used in some headache environment for the universal property,or used in a variety of factory production.
• Exceptional resistance to a wide variety of chemical process environments including strong oxidizers such as ferric acids,acetic anhydride,and seawater and brine solutions.
• Resists the formation of grain-boundary precipitates in the weld heat-affected zone,providing excellent as-welded conditions for process applications in chemical-based industries
