Fitwel Industries LLP is a well-known supplier and manufacturer of SS 321 / 321H Forged Fittings, Stainless Steel 321 Forged Socket Weld Fittings, ASTM A182 321 Stainless Steel Forged Threaded Fittings, Stainless Steel 321 Forged Fittings which is readily welded by all common methods including submerged arc. The cold work hardening rate of Stainless Steel 321 Forged Fittings makes it less machinable than 410 stainless steel, but similar to 304. Stainless Steel 321 Forged Threaded Fittings must be water quenched or fully annealed after working to re-attain maximum corrosion resistance. The following are some of the major applications of Stainless Steel 321 Forged Socket Weld Fittings: Weld equipment, Chemical processing equipment, and so on. 321 Stainless Steel Forged Fittings is often used for Pharmaceutical production, Equipment, and storage units for food processing, Waste treatment including thermal oxidizers, Aerospace applications, and so on. Stainless Steel 321H Forged Fittings is also used in Aircraft exhaust manifolds, Bellows, Furnace parts, Expansion joints, Heating element tubing, Heat Exchangers, and so on.
UNS S32100 SS Forged Coupling are indispensable to the fire protection and process piping systems, as they have good mechanical properties and are ductile, and can be hardened through work hardening. A major difference is the titanium addition in Stainless Steel 321H Forged Threaded Fittings that reduces or prevents carbide precipitation during welding. Therefore, titanium carbide in Stainless Steel 321H Forged Socket Weld Fittings is formed instead and the chromium is unaffectedly giving the material optimum corrosion resistance. 321H Stainless Steel Forged Fittings is also used for Food Processing – equipment and storage, Waste Treatment – thermal oxidizers, Petroleum Refining – polythionic acid service, etc. SS 321H Forged Fittings is as well used for High temperature, chemical process, heat exchanger tubes, Refineries, High-temperature steam service, and so on. Also We offer wide range of Stainless Steel ASTM A182 321 Forged Fittings such as SS 321 Forged Elbow, SS 321H Equal Tee, SS 321 Coupling, SS 321H Pipe Cap, SS 321 Union, SS 321 Bushing, SS 321 Plug, SS 321 Pipe Nipple, SS 321H Street Elbow.
