ASTM A240 321 Stainless Steel Coil / EN 1.4541 Stainless Steel Coil Thickness 0.4 - 16.0mm
Alloy 321 (UNS S32100) is titanium stabilized austenitic stainless steel coil with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness.
Alloy 321H (UNS S 32109) stainless steel coil is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the coil enables dual certification.
Alloy 321 stainless steel coil cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.
