253MA Stainless Steel

Conquest Steel & Alloys is a supplier and stockholder of 253MA Stainless Steel is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. UNS 30815 and 253 MA maintains its heat resistant properties by advanced control of micro-alloy additions. 253MA contains a fairly low nickel content, which gives it some advantage in reducing sulphide atmospheres when compared to high nickel alloys. The inclusion of high chromium, silicon, nitrogen and cerium contents gives the steel good oxide stability, high elevated temperature (creep) strength and excellent resistance to sigma phase precipitation. The austenitic structure gives this grade excellent toughness, even down to cryogenic temperatures. The high mechanical strength of Conquest steel & alloys 253 MA allows for thinner tube wall constructions compared with using materials of the ASTM 310 type. Despite the material's high strength, ductility is not reduced, and good formability is maintained. A wide variety of components requiring high strength at elevated temperatures such as heat exchangers, kilns, stack dampers and oven components are common applications for 253 MA.
