253MA Stainless Steel Plate

Stainless 253 MA, also name as 1.4835 stainless steel is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. 253 MA maintains its heat resistant properties by advanced control of micro alloy additions. The use of rare earth metals in combination with silicon gives superior oxidation resistance up to 2000 F degree. Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys. 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.

Performance Profile

253 MA Creep Rupture Strength
253 MA is a lean austenitic heat resistant alloy with high strength and outstanding oxidation resistance. It offers an excellent combination of creep strength along with excellent resistance to oxidation, sulfidation, and erosion at high temperatures in an alloy containing just 11% nickel. Because of its lean chemistry, 253 MA is very economical compared to most heat resistant alloys.
