What is a Stainless Steel 321h Flanges ?

Stainless Steel 321H Flanges has oxidation resistant to 1600 ° F. SS Slip on 321H Flanges is developed to provide an 18-8 type alloy with improved inter-granular-corrosion resistance. SS 321H Flanges is not subject to weld decay (inter-granular corrosion) when exposed to mildly corrosive environments. SS 321H Blind Flanges is a titanium stabilized chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition. SS 321H Weld Neck Flanges is an excellent choice for various applications ranging from oil refinery equipment to automotive exhaust systems. SS 321H Plate 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 321H Socket Weld Flanges up to 700 ° C for 1 to 2 hours and air cool. SS 321H Threaded Flanges contains 18 % chromium, 8 % nickel and a substantial addition of titanium.
