Aditya Stainless has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 253MA Pipe Fittings right in Kolkata, India. We specialize in providing robust and heat-resistant solutions tailored for high-temperature and corrosive settings. SS 253MA (UNS S30815) is an austenitic stainless steel crafted to deliver outstanding oxidation resistance, impressive strength at high temperatures, and top-notch performance in environments reaching up to 1150°C. Our range of 253MA pipe fittings, which includes elbows, tees, reducers, and caps, finds its place in furnaces, petrochemical plants, heat exchangers, and flue gas systems. These fittings are perfect for industries that demand thermal stability, mechanical strength, and a long service life even in extreme conditions.
Stainless Steel 253MA Pipe Fittings are made up of about 21% chromium, 11% nickel, 1.7% silicon, along with trace amounts of rare earth metals and nitrogen, all of which boost creep strength, oxidation resistance, and thermal stability. This alloy boasts a tensile strength of at least 600 MPa, a yield strength of 310 MPa or more, and an elongation of around 40% at room temperature. Even when the heat is on, 253MA maintains impressive mechanical strength and stands up to scaling and carburization. These characteristics make it an excellent choice for applications that involve thermal cycling, high stress, and oxidizing conditions where standard stainless steels might not hold up.
