The 321 SS coil is part of the stainless-steel austenitic family. 321 stainless steel is a 304-grade that contains a titanium stabilizer. It is an ideal choice for some applications where high heat temperature is an issue. You can use it for up to 900°C applications, unlike 304-grade which normally uses only up to 500°C.
