253MA (UNS S30815, WNR 1.4835) is a kind of heat resistant stainless steel developed on the basis of 21cr-11ni stainless steel by alloying rare earth elements CE and CN. Generally, 253MA is austenite. Due to the interaction of rare earth elements and silicon, the material still has good oxidation resistance at 1150 ℃.
However, the existence of cyanide, carbon, rare earth elements and alkali metal oxides makes 253MA have the same stress rupture strength as Ni based alloy. Therefore, 253MA can replace the expensive nickel base alloy, and can be widely used in high temperature parts with working temperature above 900 ℃ and pressure bearing occasions below 900 ℃. |

| 253MA Genenal Introduction | |||||||||||
| 253 MA is a stainless steel with excellent oxidation and creep resistance in cyclic conditions that is best employed in temperatures up to 1150 °C/2100 °F. There is a slight susceptibility to embrittlement during continuous operation at 600–850 °C/1110–1560 °F. | |||||||||||
