321 Stainless Steel Flange Manufacturer

Specialized Stainless Steel 321 Flanges Manufacturer, ASTM A182 F321 Flanges Dimensions.

Marcel Piping Projects Supply PVT LTD 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 are developed to supply 18-8 alloys type with their inter-granular corrosion resistance. Stainless Steel 321H Flanges isn’t subject to weld decay (inter-granular erosion) when exposed to mildly corrosive surroundings. Stainless Steel 321 Slip On Raised Flanges is a titanium stabilized chromium-nickel authenticate stainless steel with good strength and excellent erosion resistance, as supplied in the annealed condition. Stainless Steel 321 Blind Flanges are excellent choice for many applications ranging from oil and gas refinery equipment’s to automotive exhaust system. Stainless Steel 321 Weld Neck Flanges can be formed and drawn, high pressure are needed and other spring back is encountered than carbon steel. Stress Relief Heat this SS 321 Socket Weld Flanges are up to 700 ° C for 1 to 2 hours and air cool. Stainless Steel 321 Threaded Flanges contain 18 chromium, 8 nickel and substantial addition of titanium. Stainless Steel 321 Spectacle Blind Flanges has like erosion resistance 304 Stainless Steel. Stainless Steel 321 Lap Joint Flanges isn’t suitable at temperature 1700 ° F. Titanium is added to the composition of Stainless Steel 321H Ring common Type Flanges to suppress grain boundary chromium carbide rush and reduce susceptibility to inter-granular corrosion.
