Alpha Overseas manufactures and trades SS 321 Forged Fittings, which is today used almost exclusively for service within the sensitizing temperature range (450 Degree C – 850 Degree C). Alloy 321 Forged Socket Weld Elbow Fittings is preferred steel, where the niobium performs the same carbide stabilisation task but can be transferred across a welding arc. Grade 321 Forged Threaded Elbow Fittings offers higher creep and stress-rupture properties than Type 304 and, particularly, Type 304L which might also be considered for exposures where sensitization and intergranular corrosion are concerns. Type 321 Forged Socket Weld Tee Fittings is used where corrosive conditions are not too severe; also because of its resistance to scaling and vibration fatigue. AISI 321 Forged Threaded Tee Fittings is also used extensively for applications where the addition of titanium and its stabilizing effect as a carbide forming element allows it to be welded and/or used within the carbide precipitation range 430 Degree C – 870 Degree C without the risk of intergranular corrosion.
Fatigue or endurance limits (strength in bending) of austenitic 321 Stainless Steel Forged Fittings in the annealed condition are about one-half the tensile strength. Stainless Steel 321 Forged Threaded Fittings is as well used in firewalls, boiler casings, stack liners, welded pressure vessels, etc.
In order to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking in service temperatures at 1500 Degree F – 1650 Degree F, an air cool may be used in Stainless Steel 321 Forged Socket Weld Fittings.
