Stainless Steel 253MA Flats, designed specifically for high-temperature and demanding industrial environments. 253MA is an advanced austenitic stainless steel grade known for its exceptional strength, oxidation resistance, and excellent performance at elevated temperatures. SS 253MA flats are ideal for industries where heat resistance and long service life are critical.
Grade 253MA (UNS S30815) is a lean austenitic heat-resistant alloy designed for high strength and outstanding oxidation resistance in temperatures up to 1150°C. Stainless Steel 253MA flats are micro-alloying addition of Rare Earth Metals (REM) combined with a high nitrogen content. This chemical synergy creates a tightly adherent oxide scale that resists spalling, even during rapid thermal cycling.
