At Nascent Pipe & Tubes, we specialize in supplying high-grade 253 MA Pipes that conform to international quality standards and ensure outstanding performance in extreme environments. These pipes are manufactured using alloy 253 MA, designated by the UNS S30815 number and widely known by its ASTM designation ASTM A312. Designed for elevated temperature service, 253 MA is an advanced austenitic stainless steel that combines excellent oxidation resistance with high strength and good structural stability at elevated temperatures, making it ideal for industrial applications involving heat and corrosion.
253 MA (UNS S30815) contains a carefully balanced chemical composition with significant amounts of chromium, nickel, nitrogen, and rare earth metals, which provide excellent resistance to oxidation and carburization. This alloy is known for its superior strength at temperatures up to 1150°C and remarkable resistance to thermal fatigue. The controlled nitrogen content enhances its creep strength, while the rare earth elements improve oxidation resistance and facilitate the formation of a strong and adherent oxide layer. As a result, our ASTM A312 253 MA pipes perform exceptionally well in heat exchangers, furnace parts, radiant tubes, petrochemical refineries, and power generation units.
