Austenitic chromium-nickel stainless steel alloyed with nitrogen and rare earth metals for superior high-temperature performance.
Exceptional oxidation resistance at temperatures up to 1150°C (2100°F), especially under cyclic heating conditions.
High creep strength and structural stability for reliable service in demanding thermal environments.
Good weldability and formability with excellent resistance to combustion gases and carburizing atmospheres
253MA stainless steel is a high-performance austenitic stainless steel designed for excellent strength and oxidation resistance at elevated temperatures.
With the addition of rare earth elements and optimized alloy composition, 253MA provides superior performance compared to conventional heat-resistant grades such as 310S. It is widely used in high-temperature industrial environments
