RA 253 MA® was developed over 30 years ago when the need for a heat resistant stainless steel with high strength, while maintaining good oxidation resistance was present in the industry.

253 MA 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. while maintaining good oxidation resistance was present in the industry. The lean 11% nickel content of RA 253 MA is a key contributor to being cost effective and stable. With the addition of rare earth elements, RA 253 MA still performs well at temperatures up to 2000°F (1093°C), similar to that of 310 stainless steel.
