Alpha Overseas(AOS) is one of the eminent manufacturers that offer Stainless Steel 904L Forged Fittings, which is a high-alloy austenitic stainless steel with low carbon content. Stainless Steel 904L Forged Socket Weld Fittings has high resistance to crevice and stress corrosion cracking. Stainless Steel 904L Forged Threaded Fittings is non-magnetic, and offers excellent toughness, weldability and formability. SS 904L Forged Fittings also has a high resistance to pitting in chloride solutions, a high resistance to both stress corrosion cracking and crevice. The combination of high chromium and nickel content in Alloy 904L Forged Pipe Fittings, coupled with additions of copper and molybdenum, assure good to excellent corrosion resistance. The nickel content makes Grade 904L Forged Elbow Pipe Fittings quite resistant to chloride SCC and the low proportion of carbon makes it resistant to intergranular corrosion. Slow speeds and positive feeds will minimize the tendency of Type 904L Forged Tee Pipe Fittings to work harden and glaze. AISI 904L Forged Cross Pipe Fittings is more expensive than 316L and thus 904L has been used in pharmaceutical applications in the past.
SS 904L Forged Coupling Pipe Fittings is one of the few stainless steels that at temperatures of up to 35 Degree C / 95 Degree F provide full resistance in dilute sulphuric acid environments within the entire range of concentration, from 0 % to 100 %. 904L Stainless Steel Forged Fittings contains high amounts of expensive ingredients, such as nickel and molybdenum.
