Specification: ASTM B 622/ ASME SB 622 Maximum expose temperature: 677°C / 1250°F
Alloy C22 is a nickel-chromium-molybdenum alloy with tungsten and extremely low carbon and silicon contents. This alloy enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. It had an exceptional resistance to a wide variety of chemical process environments including strong oxidizing such as ferric acid, acetic anhydride, wet chloride and brine solutions.
