Based in Kolkata, India, Khush Sheets and Plates is a reputable manufacturer and supplier of stainless steel 253MA angles that provides high-temperature stainless steel solutions for demanding industrial applications. Austenitic stainless steel SS 253MA is renowned for its exceptional strength at high temperatures and exceptional resistance to oxidation. Our 253MA angles are perfect for use in structural frameworks subjected to high temperatures because they are precisely manufactured to meet international quality standards. With a significant presence in the petrochemical, furnace equipment, and thermal processing sectors, we guarantee that our customers receive robust, high-performing products that can withstand harsh environments.
20–22% Chromium, 10–12% Nickel, 1.4–2.0% Silicon, 0.05–0.10% Nitrogen, and trace amounts of Carbon, Manganese, and Rare Earth Metals make up stainless steel 253MA Angle. Up to 1150°C, this composition offers remarkable oxidation resistance and high-temperature strength. The alloy has an elongation of about 40%, a yield strength of 310 MPa, and a tensile strength of roughly 600–750 MPa. 253MA is perfect for structural elements in heat-intensive settings like furnaces and reactors because it resists carburisation and retains mechanical integrity under thermal cycling.
