253 MA Sheet & Plate

253 MA Sheet & Plate

253 MA Sheet & Plate is a high-performance stainless steel alloy engineered for superior oxidation resistance and mechanical strength at elevated temperatures, particularly around 1150°C. This material excels in high-temperature environments due to its unique combination of high chromium, silicon, nitrogen, and rare earth elements like cerium, which enhance its oxidation stability and structural integrity. Known in some circles by the proprietary designation 2111HTR, 253 MA remains an ideal choice for applications demanding long-term durability, thermal stability, and ease of fabrication under extreme conditions.

At European Special Alloys W.L.L., we provide top-quality 253 MA sheets and plates designed to withstand aggressive environments such as those found in heat treatment, power generation, petrochemical, and furnace construction industries. With a relatively low nickel content, 253 MA offers resistance to reducing sulfur-containing atmospheres while maintaining excellent strength and structural reliability. The alloy's chemical composition also provides resistance to sigma phase formation, ensuring that the material retains its mechanical properties even during prolonged exposure to high temperatures.
