Stainless Steel 253 MA is an incline austenitic heat resistant alloy with high strength and extraordinary oxidation resistance. 253 MA keeps up its heat resistant properties by advanced control of micro alloy additions.
The utilization of uncommon earth metals joined with silicon, which provides better oxidation resistance up to 2000°F. Nitrogen, carbon and a dispersion of uncommon earth and alkali metal oxides join to give creep rupture strength similar to the nickel base alloys. A wide variety of parts requiring high strength at high temperatures for example heat exchangers, kilns, stack dampers as well as oven components are common applications for Stainless Steel 253 MA.
