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. It is designed to fill the gap between standard 304/316 stainless steels and more expensive high-alloy steels and nickel-based alloys.
