ASTM A403 WP304 • Stainless Steel Fittings • 304/304L Buttweld Fittings • 304/304L Pipe Fittings Supplier
304 and 304L Pipe Fittings supplied by Siddhagiri Metals and Tubes are of best quality and highly corrosion-resistant. Our ASTM A403 WP304 Fittings inventory is available in random lengths or cut to specific lengths to meet your exact requirements. Over the years, we have gained unique experience with pipes for different applications. We control the manufacturing process from raw material to finished product, with a constant focus on quality to meet demanding specifications.
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. Stainless Steel 304 Pipe Fittings and Stainless Steel 304L Pipe Fittings are manufactured and finished according to international standards ASTM A403 WP304, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of 304/304L 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 elbows are mandrel formed to ensure consistency.
Stainless Steel Return Bend Fittings— Bends are similar to elbows with different bending radiuses. ASTM A403 Bends are supplied as long radius return bends and short radius return bends.
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.
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.
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.
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.
Stainless Steel Pipe Reducer Fittings— Reducers are supplied as Eccentric Reducer, Concentric Reducer and Conical Reducer or Bell Shaped Reducer.
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.
Stainless Steel Pipe Fittings manufactured by Siddhagiri Metals and Tubes are designed for high performance under extreme environments. Moreover, our Pipe Fittings have wall thickness designed with ample erosion and corrosion allowance .We stock a full range of 304/304L pipe fittings in sizes 1/8” NB to 24" NB in SCH5, SCH10, SCH40, SCH80, SCH160, SCH XS, SCH XXS.

Properties of 304/304L alloy
304/304L Cold Forming
Type 304/304L is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.
304/304L Hot Forming
Type 304/304L can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.
Type 304/304L is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.
Type 304/304L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308L/ER308L filler metals should be used with Type 304/304L steel, but the molybdenum-containing austenitic stainless steel filler metals may also be considered.
304/304L Heat Treatment
Annealing: Type 304/304L should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type 304/304L cannot be hardened by heat treatment. However, Type 304/304L can be hardened by cold working.
