253MA S30815 F45, AUSTENITIC Cr-Ni-Si HEAT RESISTING STEEL

Description

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, 253 MA is very economical compared to most heat resistant alloys.

Applications

Boiler Nozzles, Cyclones, Bar Baskets, Radiant Tubes,
