This Stainless Steel 321 Stub End resists oxidation to 1500 Degree F (816 Degree C) and has higher creep and stress rupture properties than alloys 304 and 304L. Our Stainless Steel 321 Bend was developed for enhanced creep resistance and for higher strength at temperatures above 1000 Deg F (537 Degree C). This Stainless Steel 321 Reducer has good forming and welding capabilities, and is widely used in running temperature atmospheres. Buy SS 321 Cross at reasonable cost from us. Our Stainless Steel 321 Tee is the higher carbon (0.04 – 0.10) version of the alloy. In most instances, the carbon content of the plate enables dual certification. This Stainless Steel 321 Elbow can be easily welded and processed by standard shop fabrication practices. Our Stainless Steel 321 Butt Weld Fittings cannot be hardened by heat treatment, only by cold working. This SS 321 Pipe Fittingshas excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500 Degree F (427 – 816 Degree C).
