Composition of Stainless Steel 321 / 321H Coil/Foil/Shim
Stainless Steel 321/321H Coils, Foils, and Shims are manufactured from austenitic stainless steel containing iron, chromium, and nickel, with titanium added as a stabilizing element and controlled carbon levels that influence high-temperature performance. Chromium forms a protective oxide layer on the material surface, helping resist corrosion and oxidation in many service environments, while nickel contributes to toughness, ductility, and overall durability. Titanium stabilization helps limit chromium carbide precipitation during elevated-temperature exposure, supporting resistance to intergranular corrosion under suitable operating conditions. The higher-carbon grade, SS 321H, is designed to provide improved creep strength at elevated temperatures compared with standard SS 321, making it a suitable option for certain high-temperature applications. Both grades offer useful fabrication characteristics and can be processed into coils for further manufacturing, thin foils for specialized components, and precision shims for spacing and adjustment. With their combination of heat resistance, mechanical reliability, fabrication versatility, and dependable performance, SS 321/321H products are used in heat exchangers, chemical processing equipment, power generation systems, industrial machinery, and other engineering applications involving elevated temperatures. Grade selection should be based on the operating environment, temperature range, fabrication method, and project specifications.
