What is 253MA stainless steel material?
253 ma stainless steel is a kind of heat resistant Austenitic stainless steel which is with high creep strength
and good resistance to corrosion.
Except for the alloy element chromium and nickel, 253 ma stainless steel also contains a small amount of
Rare Earth Metals( REM), so as to improve its oxidation resistance significantly. Addding the Nitrogen to improve
the creep properties and make it to be fully austenitic stainless steel. Although the chromium and nickel content is
relatively low, but this kind of stainless steel has many similar properties with the high alloyed stailess steel and
nickel base alloy in many cases.
253 ma is widely applied in sintering, blast furnace equipment, steel melting equipment, furnace and continuous
casting equipment, rolling mill (furnace), heat treatment furnace and accessories, mineral and cement production
equipment, etc. 253 ma stainless steel can be resistent to 900 ℃.
