Alpha Overseas(AOS) manufactures and trades SS 321 Flanges, which is advantageous for high temperature service because of its good mechanical properties. A limitation with Alloy 321 Flanges is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. Grade 321 Flanges has extensive use in aircraft parts, such as exhaust systems where operating temperatures are higher than 800 Degree F. Type 321 Flanges cannot be hardened by thermal treatment, but hardness and strength can be increased substantially by cold working, with subsequent reduction in ductility. To be a true “stabilized” grade, AISI 321 Flanges has to have Titanium (Ti) content at least 5 times of Carbon’s (C). This titanium addition in 321 Stainless Steel Flanges reduces or prevents carbide precipitation during welding and in the 800 Degree F – 1500 Degree F service conditions. Typical uses of Stainless Steel 321 Slip On Flanges include annealing covers, heavy duty and diesel automotive exhaust systems, high-temperature tempering equipment, etc. However, welded Stainless Steel 321 Blind Flanges must never be used in highly oxidising environments as it is liable to 'Knife-line' attack.
Stainless Steel 321 Weld Neck Flanges offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.
In dynamic applications of SS 321 Socket Weld Flanges, fatigue strength is also important to consider.
