GNEE Steel Products Description
654SMo, also called S32654 or 1.4652, is a super austenitic stainless steel containing 23% nickel, 25% chromium and 7% molybdenum. Its corrosion resistance is comparable to that of the best nickel-based alloy. As the nitrogen content of 654SMo is twice as high as 254SMo , its intensity is higher than 904L and 254SMo. There are two smelting method for 654SMo super austenitic stainless steel: 1) the currently popular argon-oxygen decarburization refining smelting in abroad -VOD or AOD; 2) continuous casting method used for producing stainless steel.
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.
