ASTM A312 253MA / UNS S30815 / EN 1.4835 Stainless Steel Seamless Pipe

ASTM A312 253MA / UNS S30815 / EN 1.4835 Stainless Steel Seamless Pipe

253MA is a heat-resistant austenitic stainless steel alloy. It contains chromium, nickel, and nitrogen as its main alloying elements. This alloy offers excellent oxidation resistance at high temperatures up to 1150°C, making it suitable for use in high-temperature applications such as furnace components, heat exchangers, and exhaust systems. They are commonly used in industries such as chemical processing, power generation, and oil and gas exploration.
