Stainless 321 / AISI 321
Stainless 321 is a chromium-nickel steel which was developed with improved intergranular-corrosion resistance. Stainless 321 is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals. Type 321 should be used for applications requiring heating between 800 °F and 1650 °F such as aircraft collector rings, and exhaust manifolds, expansion joints, and high temperature chemical process equipment.
