321 SS Plates
321 stainless steel plates are 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°C where 304 is normally used up to 500°C.

Description
Product information
321 SS is a titanium stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular-corrosion resistance. This material is stabilized against chromium carbide formation by the addition of titanium. Since titanium has a stronger affinity for carbon than chromium, titanium carbide precipitates within the grains instead of forming at the grain boundaries.
321 stainless steel should be considered for applications requiring intermittent heating between 800ºF (427ºC) and 1650ºF (899ºC), or for welding under conditions which prevent a post-weld anneal. 321 stainless steel is non-magnetic.
