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.
Available forms are seamless pipe, welded pipe,
seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe
fittings and flanges. |
