Super Austenitic Fittings (904L / SMO 254)

Super austenitic stainless steel fittings in 904L and SMO 254 (S31254) offer significantly higher corrosion resistance than standard 316L, particularly against chloride pitting and crevice corrosion. With high molybdenum and nitrogen content, these alloys bridge the gap between standard austenitic stainless steels and nickel alloys. Shree Raj Steels supplies these fittings from globally approved mills with full traceability.
