Aditya Stainless stands out as a leading manufacturer and supplier of Stainless Steel 253MA Pipes in Kolkata, India, delivering high-quality piping solutions designed for high-temperature and oxidizing environments. SS 253MA (UNS S30815) is an austenitic stainless steel crafted for remarkable strength, oxidation resistance, and long-lasting durability at temperatures soaring up to 1150°C. These pipes are perfect for industries that demand reliable performance under thermal stress, including refineries, power plants, cement kilns, and heat treatment facilities. Offered in various sizes, schedules, and types (both seamless and welded), 253MA pipes excel in both static and cyclic heat applications.
Stainless Steel 253MA Pipes are made up of approximately 21% chromium, 11% nickel, and 1.7% silicon, along with trace amounts of nitrogen and rare earth metals, which provide excellent oxidation and creep resistance. These pipes boast a tensile strength of at least 600 MPa, a yield strength of at least 310 MPa, and impressive elongation of around 40%, ensuring they maintain strength and ductility even at elevated temperatures. They are resistant to scaling, carburization, and sulfidation, even when subjected to thermal cycling. With good weldability and fabricability, 253MA pipes are perfect for high-temperature pressure systems where mechanical stability, corrosion resistance, and a long service life are essential.
