321 stainless steel plate

321 stainless steel plate is part of the austenitic family of stainless steel. 321 is basically a 304 grade containing a stabilizer of titanium. Type 321 is a good choice for applications where heat is an issue. 321 can be used in applications up to 900 degrees Celsius where 304 is normally used up to 500 degrees Celsius. Grade 321 stainless steel plate has excellent forming and welding characteristics. It does not polish well so would not be used for decorative applications. Detect-Metals stocks a wide range of sizes in 321 stainless certified to AMS 5510, ASTM A 240, and SA 666.
