Duplex Steel – 253 MA

Stainless 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. The use of rare earth metals in combination with silicon gives superior oxidation resistance up to 2000° F. Nitrogen, carbon and a dispersion of rare earth and alkali metal oxides combine to provide creep rupture strength comparable to the nickel base alloys. A wide variety of components requiring high strength at elevated temperatures such as heat exchangers, kilns, stack dampers and oven components are common applications for 253 MA


Some of the typical applications of duplex steel grade 253 MA are listed below:

  • Boiler Nozzles.
  • Corrugated Boxes.
  • Cyclones.
  • Bar Baskets.
  • Radiant Tubes.
