Nizar Sheetsandplates, based in Amman, Jordan, is a trusted manufacturer and supplier of high-performance stainless steel products designed for extreme service conditions. They offer Stainless Steel 253MA Angles, a cutting-edge austenitic stainless steel grade known for its remarkable strength and oxidation resistance at high temperatures. These angles are crafted with precise dimensional accuracy and consistent quality, making them ideal for structural and fabrication applications in high-heat environments. Nizar Sheetsandplates is committed to meeting international standards and providing reliable supplies for demanding industrial needs.
Stainless Steel 253MA is a high-alloy austenitic stainless steel that contains around 20–22% chromium and 10–12% nickel, along with silicon, nitrogen, and rare earth elements. This carefully balanced composition gives it exceptional oxidation resistance up to about 1150 °C and superior high-temperature strength compared to standard stainless steels. The material boasts good tensile and yield strength, excellent creep resistance, and a stable microstructure even at elevated temperatures. Plus, it maintains good weldability and structural integrity during thermal cycling.
