Adam Stainless proudly offers top-notch **Stainless Steel 321 coils** right from Canberra, Australia. These coils are designed to provide outstanding corrosion resistance, thermal stability, and mechanical strength. Crafted to meet rigorous international standards, they boast consistent thickness, a smooth surface finish, and excellent formability. If you’re looking for materials that can withstand high-temperature oxidation and stress corrosion cracking, Adam Stainless’s Stainless Steel 321 coils are the perfect choice, ensuring reliable performance even in the toughest environments.
Stainless Steel 321 is an austenitic stainless steel alloy that contains about 17–19% chromium and 9–13% nickel, with titanium added to prevent carbide precipitation during welding and exposure to high temperatures. This stabilization not only enhances resistance to intergranular corrosion but also boosts mechanical stability at elevated temperatures, reaching up to 900°C. The alloy features a tensile strength ranging from 515 to 620 MPa and a yield strength close to 205 MPa, all while maintaining toughness and ductility for a variety of industrial applications.
