Stainless Steel 321 Blind Raised Flanges is an excellent choice for various applications ranging from oil refinery equipment to automotive exhaust systems. Stainless Steel 321 Weld Neck Flanges can be readily formed and drawn, however, higher pressures are required and more spring-back is encountered than for carbon steel and ferrite stainless steels. Stress Relief – Heat this Stainless Steel 321 Socket Weld Flanges up to 700 ° C for 1 to 2 hours and air cool. Stainless Steel 321 Threaded Flanges contains 18 % chromium, 8 % nickel and a substantial addition of titanium.
Stainless Steel 321 Spectacle Blind Flanges has comparable corrosion resistance and machinability to Stainless Steel 304. Stainless Steel 321 Lap Joint Flanges is not suitable for work at temperatures below 1700 ° F (927 ° C). Titanium is added to the composition of Stainless Steel 321H Ring joint Type Flanges to suppress grain boundary chromium carbide precipitation and reduce susceptibility to inter-granular corrosion.
