Alloy 800 has a high chromium content and sufficient nickel content, so it has a high temperature corrosion resistance, and is widely used in industry. In chloride, low concentration of NaOH aqueous solution and high temperature and high pressure water, it has excellent stress corrosion cracking resistance, so it is used to manufacture stress corrosion cracking resistance equipment.
Its corrosion resistance is better than the general austenitic stainless steel, It is also superior to Alloy 600 and Monel 400 in the manufacture of corrosion stress rupture resistant equipment.
