Siddhagiri Metals and Tubes is an ISO 9001:2015 certified suppliers of AISI 321H Pipe Fittings as per ASTM A403 WP321h specification. All forms of SS 321H Seamless and Welded Pipe Fittings available in stock.
A fitting is used in pipe systems to connect straight pipe or tubing sections, adapt to different sizes or shapes and for other purposes, such as regulating fluid flow. Pipe Fittings are used in a piping system to change direction or function, which is mechanically joined to the system. The simplest way to achieve this is to bend the pipe in the direction required, but this process will stretch and thin the outer wall of the pipe whilst thickening and wrinkling, the inner wall of the pipe. This results in flow resistance and accelerated wall erosion. 321H Pipe Fittings are manufactured and finished according to international standards ASTM A403 WP321H, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of 321H Buttweld Fittings includes Elbows, Tees, Cross, Cap, Reducers, Collars, Bends in all sizes and forms.
Stainless Steel Elbow Fittings—Stainless Steel Pipe Elbows are installed between two lengths of pipe or tube allowing a change of direction by 180°, 90° or 45°. The ends are machined for Butt Welding when the two ends differ in size, it is called a Reducer or, Reducing Elbow. Pipe Fitting Elbows are available as 180° elbows, 90° elbows or 45° elbows in 1D, 1.5D, 2D, 3D, 5D, 6D, 8D, 10D radius as short and long radius elbows. All ASTM A403 / ASME SA403 elbows are mandrel formed to ensure consistency. 321H Stainless Steel Elbow Fittings and Stainless Steel Elbow Fittings is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Return Bend Fittings— Bends are similar to elbows with different bending radiuses. ASTM A403 / ASME SA403 Bends are supplied as long radius return bends and short radius return bends. 321H Stainless Steel Return Bend and Stainless Steel Return Bend is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Pipe Cross Fittings—Pipe Fitting Cross are used in several industries for providing the leak free and torque free sealing in any piping or tubing connection known for their close tolerances. 321H Stainless Steel Pipe Cross and Stainless Steel Pipe Cross is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Cap Pipe Fittings—The function of a Pipe Cap is to block off the end of a line in an industrial piping system. Pipe Cap is fitted by placing the end cap over the open line and welding around the joint. 321H Stainless Steel End Cap and Stainless Steel End Cap is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Tee Pipe Fittings—Pipe Fitting Tee is widely used in industrial piping systems to merge or divide fluids and do not require special tubing preparation before installation. Tees are available in different threading specifications and are engineered to close tolerances and precise dimensions. 321H Stainless Steel Tee Fittings and Stainless Steel Tee Fittings is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Stub Ends Pipe Fittings—Stub Ends are installed in pairs and mated together with two Lap-Joint Flanges. The surface of the stub end has a phonographic serrated gasket surface which prevents leakage at the joint. Using stub ends allows sections of the line to be opened for cleaning, inspection or quick replacement, etc, without the need to re-weld. 321H Stainless Steel Stub End and Stainless Steel Stub End is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Pipe Reducer Fittings— Reducers are supplied as Eccentric Reducer, Concentric Reducer and Conical Reducer or Bell Shaped Reducer. 321H Stainless Steel Pipe Reducer and Stainless Steel Pipe Reducer is in ready stock with Siddhagiri Metals and Tubes.
Stainless Steel Pipe Coupling— Couplings are used to merge two equal ends in a piping system. Couplings are classified as half-coupling and full-coupling. 321H Stainless Steel Pipe Couplings and Stainless Steel Pipe Couplings is in ready stock with Siddhagiri Metals and Tubes.

Properties of AISI 321H Stainless Steel
Type 321 Cold Forming
Type 321 is easliy cold formed due to its ductile nature.
Type 321 Hot Forming
Type 321 can be readily formed and drawn.
Type 321 Machining
Type 321 is less machineable than Type 410 Stainless Steel.
Type 321 Welding
Type 321 is easily weldable by all standard techniques. No post weld treatment is required.
Type 321 Heat Treatment
Type 321 is non-hardenable by heat treatment. 321 is annealed by heating it to 1750 – 2050 °F (954 – 1121°C), then water quench or air cool.
