SS UNS S32100 Pipe Flanges, ANSI B16.5 SS 321 Orifice Flange, Stainless Steel 321 Pipe Flanges, 150# ANSI SS 321 Flanges, SS 321 Spacer, Stainless Steel 321 Slip On Flanges Supplier in Mumbai, India.
Trinity Alloys Inc is a well-known firm that manufactures and distributes a wide range of SS 321 / 321H Flanges, which has oxidation resistant to 1600 ° F. Stainless Steel 321 Flanges is developed to provide an 18-8 type alloy with improved inter-granular-corrosion resistance. Stainless Steel 321H Flanges is not subject to weld decay (inter-granular corrosion) when exposed to mildly corrosive environments. Stainless Steel 321 Slip On Raised Flanges is a titanium stabilized chromium-nickel austenitic stainless steel with good strength and excellent corrosion resistance, as supplied in the annealed condition. Stainless Steel 321 Blind Raised Flanges is an excellent choice for various applications ranging from oil refinery equipment to automotive exhaust systems.
SS 321H Spectacle Blind Flanges, SS 321H Spade Flange, SS GOST 08Х18Н10 Screwed Flanges Stockist, ANSI B16.5 SS F321 Ring Type Joint Flanges, SS 321 Nippo Flanges, Stainless Steel F321 Industrial Flanges Stockholder, ASME SA182 SS 321H Lap Joint Flange, SS Grade F321 Forged Flanges Manufacturer.
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.
