Stainless Steel 321 Flanges

Stainless steel flanges are made with the addition of various other elements in trace amounts to enhance the property of the product. Stainless Steel 321 Flanges is one such flange that is made up of austenitic steel and is stabilized using titanium in trace amounts. The addition of titanium enhances the corrosion resistance property of these flanges. SS 321H Blind Flanges manufacturer In India supplies these flanges in a size range of ½ inch to 48 inches. However, the diameter and wall thickness of these flanges may vary. The difference in pressure rating of these changes is due to the difference in dimensions. 

6 Inch 321 SS Weld Neck Flanges have a pressure rating ranging from class 150 to class 2500. They have a melting point of 1454 degrees C and a working temperature of 870 degrees C. These flanges are available in various faces such as flat face, ring type joint face, and raised face to name a few. ASTM A182 F321H Slip On Flange is available in threaded, plate, screw, or forged type. These flanges are used in oil and gas, chemical, and petroleum industries. Werkstoff Nr. 1.4541 Socket Weld Flanges are also used in applications such as nuclear power plants, heat exchangers, and boilers. 

321 Stainless Steel Threaded Flanges are also used in the natural gas, water pipeline, and fabrication industry. They resist oxidation up to 1600 degrees C and have improved intergranular corrosion. They offer exceptional durability and strength and are supplied in the annealed condition. ASME SA182 F321 Large Diameter Plate Flanges offer features such as dimensional accuracy, and minimum cost of maintenance. We at Fastwell can even customize these flanges as per the requirement of the application if required.
