253MA Stainless Steel Pipe ASTM A312 UNS S30815 / EN 1.4835
Grade 253MA provides excellent service properties & ease of fabrication at high temperatures. It provides superior service to Grade 310 in carbon， nitrogen and sulphur containing atmospheres and resists oxidation at temperatures up to 1150°C. 253MA gives some advantage in reducing sulphide atmospheres when compared to high nickel alloys and to Grade 310， due to its fairly low nickel content. 253MA steel provides good oxide stability， high elevated temperature strength and excellent resistance to sigma phase precipitation due to its properties of inclusion of high silicon， nitrogen and cerium. Even down to cryogenic temperatures， the austenitic structure gives this grade excellent toughness.
