IV. Alloy 20 material characteristics
Alloy 20 alloy corrosion-resistant alloy is a chromium nickel-molybdenum copper solid solution reinforced iron-nickel-based alloy. Its characteristics are resistant to oxidation-reducing composite media corrosion. NS143 has good corrosion resistance in sulfuric acid, nitric acid and its mixed acid and various other redox media. NS143 can best exert its advantages in dilute sulfuric acid (concentration below 30%) environments, especially in dilute sulfuric acid (concentration below 30%), and has excellent stress corrosion resistance and good local corrosion resistance. NS143 has satisfactory corrosion resistance characteristics in many chemical process media, including highly aggressive inorganic acid solutions, chlorine and various media containing chlorides, dry chlorine, formic acid and acetic acid, acid anhydride, seawater and brine, etc.
