Type 321 (UNS S32100) Description

Type 321 is a titanium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500˚F temperature range where it is stabilized against chromium carbide precipitation by the addition of titanium, which results in the precipitation of titanium carbides. Type 321 has excellent intergranular corrosion resistance after exposure to this temperature range, and this grade resists oxidation up to 1500˚F and has higher creep and stress rupture properties than 304/304L. It also possesses good low temperature toughness and is non-magnetic in the annealed condition.

Chemical Composition
Chemical Composition (wt%) limits as specified in ASTM A240 and ASME SA240

Mechanical Properties

Mechanical property requirements for annealed product as specified in ASTM A240 and ASME SA240.

Application

Instruments and construction parts in the food industry, luxury food, film and photo industry as well as for articles of daily use in the household, power station construction. Due to the Ti-alloy, the resistance to intergranular corrosion is also guaranteed in the welded condition.
