Aditya Stainless has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 253MA in Kolkata, India. They provide top-notch material solutions for industries that operate in high-temperature and corrosive settings. SS 253MA (UNS S30815) is an austenitic stainless steel crafted to deliver outstanding oxidation resistance, impressive high-temperature strength, and long-lasting structural stability, even at temperatures reaching 1150°C. Primarily designed for heat-resistant applications, it skillfully combines chromium, nickel, silicon, and rare earth elements to ensure exceptional performance. This stainless steel is perfect for creating furnace components, heat exchangers, refinery parts, kilns, and other equipment that needs to withstand thermal stress.
Stainless Steel 253MA generally consists of about 21% chromium, 11% nickel, 1.7% silicon, along with trace amounts of nitrogen and rare earth elements that boost its oxidation resistance and mechanical strength. This alloy boasts a tensile strength of ≥600 MPa, yield strength of ≥310 MPa, and an elongation of around 40% at room temperature, all while maintaining impressive mechanical properties even at higher temperatures. SS 253MA exhibits remarkable creep strength, excellent resistance to scaling, carburization, and sulfidation, and performs admirably under cyclic heating conditions. Plus, it’s easy to weld and form, making it a great choice for various industrial processing and thermal applications.
