Incoloy825 is a titanium-stabilized full austenitic nickel-iron-chromium alloy with added copper and molybdenum. Incoloy825 has resistance to acid and alkali metal corrosion in both oxidizing and reducing environments. The high nickel content makes the alloy effective in stress corrosion cracking resistance. Due to the high temperature and corrosion resistance of the alloy, inconoy825 steel tube has been widely used in petroleum, chemical industry.
