About Stainless Steel
Compare over 25 types of stainless steel to find the right material for you—all with material certificates for traceability.
Weldable 321 Stainless Steel
The titanium content of 321 stainless steel preserves corrosion resistance around weld points. This material maintains its corrosion resistance in temperatures up to 1500° F.
Foil is often used as a heat-treating wrap in temperatures up to 2000° F. It is furnished with a crimping tool.
