SS 321 Forged Fitting Details
Nowadays, SS 321 Forged Fittings are used almost exclusively in the sensitising temperature range (450°C to 850°C). The material of choice is Alloy 321 Forged Socket Weld Elbow Fittings, which allows for the transmission of niobium through a welding arc while maintaining carbide stabilisation.
Grade 321 Forged Threaded Elbow Fittings offers higher creep and stress-rupture capabilities than Type 304 and, particularly, Type 304L, which may also be taken into consideration for exposures where sensitization and intergranular corrosion are problems.
Forged socket weld tee fittings of type 321 are utilised in slightly corrosive conditions because they resist scaling and vibration fatigue. Due to the presence of titanium and its stabilising role as a carbide forming element, AISI 321 Forged Threaded Tee Fittings can be welded and/or used within the carbide precipitation range of 430 Degree C to 870 Degree C without worrying about intergranular corrosion.
Alloy 321 is a stabilised chromium-nickel stainless steel designed to increase intergranular corrosion resistance. The inclusion of titanium stabilises the alloy against the growth of chromium carbide. Applications that require intermittent heating have been considered for the alloy. Its high-temperature strength is boosted by its 0.08 percent carbon concentration, 19 percent chromium content, 9 percent nickel content, and 2 percent silicon content.
Attributes of SS 321 Forged Fittings
There are various characteristics of the fittings which make them the most preferable product among the industries. They are-
• Excellent corrosion resistibility
• High durability
• Weldability
• Sustain in high temperature
• Pitting corrosion resistance
The fatigue or endurance limitations (strength in bending) of austenitic 321 stainless steel forged fittings are approximately half that of their tensile strength. Stainless steel 321 forged threaded fittings are also used in firewalls, boiler casings, stack liners, welded pressure vessels, etc.
In service temperatures between 1500°F and 1650°F, an air cool may be used in Stainless Steel 321 Forged Socket Weld Fittings to offer the best defence against intergranular corrosion and polythionic acid stress corrosion cracking.
