Stainless steel TP 321(UNS S32100) is a titanium stabilized chromium nickel
austenitic stainless steel with
corrosion resistance similar to SS 304/304L. SS 321 is also known as 1.4541
in Europe. SUS 321 is typically used in the 800-1500˚F temperature range. 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 stainless steel 304/304L.
