Hastelloy C-22 UNSN06022 BAR/Bolt/ Sheet/Pipe

Why Hastelloy C-22?

• 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.
