Alpha Overseas(AOS) trades SS 317L Forged Fittings, which is developed primarily to resist more effectively the attack of sulphurous acid compounds. We can process our Alloy 317L Forged Socket Weld Elbow to fit your applications using our in house processing capabilities and service on your timeline. Welding can be performed in these Grade 317L Forged Threaded Elbow by using most of the conventional fusion and resistance methods, where resistance increases with molybdenum alloy content. The high levels of these elements assure our Type 317L Forged Socket Weld Tee has superior chloride pitting and general corrosion resistance to the conventional 304 / 304L and 316 / 316L grades. Some applications that use these AISI 317L Forged Threaded Tee Pipe Fittings include: Paper & pulp handling equipment, Chemical & petrochemical processing equipment. Our 317L Stainless Steel Forged Fittings is resistant to sulphuric acid concentrations up to 5 percent at temperatures as high as 120 Degree F (49 Degree C). For maximum corrosion resistance in these Stainless Steel 317L Forged Threaded Fittings, forgings should be annealed at 1900 Degree F minimum and water quenched or rapidly cooled by other means after hot working operations.
Low speeds and constant feeds will minimize the tendency of our SS 317L Forged Socket Weld Fittings to work harden. Low carbon, or simply “L”, of these Stainless Steel UNS S31703 Forged Fittings ensures resistance to sensitization during welding or when thermal processes are applied due to the low carbon in its chemical composition.
