General introduction of 253MA:
- 253mA 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
- The leaner nickel content of 253mA was not as significant of a development then as it is now
- With nickel prices fluctuating more than ever before and higher than they have ever been, the lean 11% nickel content of RA 253mA is a key contributor to being cost effective and stable. Still with the addition of rare earth elements, 253mA still performs well at temperatures up to 2000°F (1093°C), similar to that of 310 stainless steel
Performance of 253mA:
- 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, 253mA is very economical compared to most heat resistant alloys
- 253mA obtains its heat resistant properties by tight control of micro alloy additions
- The use of cerium in combination with silicon results in superior oxidation resistance to 2000°F (1093°C)
- Nitrogen, carbon, and cerium combined to provide creep rupture strength that is double that of type 310 and 309 stainless at 1600°F (871°C).
Features of 253mA:
- Oxidation resistance to 2000°F (1093°C)
- Good resistance to sulfidation
- Superior strength at elevated temperatures
- Good resistance to high temperature abrasion
