SS 253MA rod is a premium austenitic stainless steel designed specifically for excellent performance in elevated temperature conditions. Stainless Steel 253MA rods excel in high-temperature environments with superior creep strength and oxidation resistance, making them ideal for furnace and petrochemical applications.
Stainless Steel 253MA Rod (UNS S30815) is an austenitic grade with rare earth additions for exceptional oxidation resistance up to 1150°C and high creep strength. 253MA Rod maintains structural stability in cyclic thermal loads, outperforming standard grades in combustion gases. Stocked in rounds 10-150mm for heat exchanger tubes and furnace parts.
