Aditya Stainless is a well-respected manufacturer and supplier of Stainless Steel 253MA Sheets and Plates based in Kolkata, India. They serve industries that require exceptional high-temperature strength, oxidation resistance, and durability. SS 253MA (UNS S30815) is an austenitic stainless steel designed for structural applications in extreme environments, capable of withstanding temperatures up to 1150°C. These sheets and plates are commonly found in furnace equipment, thermal processing units, and petrochemical plants, thanks to their impressive creep resistance, long service life, and stability during thermal cycling. Offered in various thicknesses and finishes, 253MA sheets and plates are perfect for both fabrication and structural uses.
Stainless Steel 253MA Sheets and Plates generally consist of 21% chromium, 11% nickel, 1.7% silicon, along with trace amounts of nitrogen and rare earth elements. This unique composition provides excellent oxidation resistance and mechanical strength at high temperatures. They boast a tensile strength of at least 600 MPa, yield strength of at least 310 MPa, and an elongation of around 40%. These sheets and plates are resistant to scaling, thermal fatigue, and carburization, making them ideal for extended exposure to heat. Additionally, the alloy offers good fabricability and weldability, making it easy to work with in complex constructions and thermal equipment fabrication.
