Adam Stainless is a well-respected manufacturer and supplier of Stainless Steel 321 Flanges located in Canberra, Australia. They provide top-notch flange solutions designed for applications that demand outstanding resistance to heat and corrosion. With a strong focus on precision, reliability, and adherence to global standards, Adam Stainless ensures that their flanges meet the requirements of critical piping systems across various industries. Their SS 321 flanges are particularly suited for high-temperature environments, especially where intergranular corrosion resistance is crucial. Supported by technical know-how and a responsive supply chain, Adam Stainless has earned the trust of engineers, contractors, and fabricators all over Australia.
Stainless Steel 321 flanges consist of an austenitic steel alloy that is composed of 17-19% chromium, 9-12% nickel, and trace amounts of titanium, which usually is 5 times the carbon content. It is added for stabilization, ensuring that there would be no sensitization and no carbide precipitation during welding, making SS 321 ideal for high-temperature applications. It has excellent resistance to corrosion, such as the intergranular type, and adequate oxidation resistance in environments as high as 900°C. Its mechanical properties include a tensile strength of 505-750 MPa, yield strength of 205 MPa, and elongation of 40% in 50 mm to sustain the hostilities under severe conditions.
