Overview of 253MA austenitic stainless steel

Time:9/11/2020 1:24:00 PM

253MA is a heat-resistant austenitic stainless steel designed for applications requiring high creep strength and good corrosion resistance. Its operating temperature range is 900 ~ 1150 ℃. Because 353ma is an austenitic steel with high carbon content, the microstructure of 253MA steel contains carbides, so 253MA steel has high stability against precipitation of σ phase.

253MA heat-resistant steel was developed in the middle and late 1980s by adding cerium, lanthanum, neodymium and Praseodymium on the basis of traditional Cr Ni austenitic stainless steel and adding nitrogen microalloying. 253MA steel has a high temperature of scale formation in air, which is 1150 ℃. Variety classification: 253MA seamless pipe, 253Ma Plate, 253MA round steel, 253MA forging, 253MA flange, 253MA ring, 253MA welded pipe, 253MA steel strip, 253MA wire and 253MA matching welding materials can be supplied with various specifications.

2. Delivery status: seamless pipe: solid solution + acid white, length can be fixed; plate: solution, acid pickling, trimming; welded pipe: solid solution acid white + RT% flaw detection, forging: annealing + turning; bar is in forging state, surface polishing or turning polishing; strip is cold-rolled, solution soft, deoxidized skin; wire is delivered in solution acid wash plate or straight strip, solid solution straight strip fine polishing state.
