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. Stainless Steel 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. 904L Pipe Fittings are manufactured and finished according to international standards ASTM A403 WP904L, ASTM A403 UNS N08904, ASME B16.9, ANSI B16.9, ASME B16.28, ANSI B16.28, ANSI B16.25, MSS-SP-43 & MSS SP-75. Our range of 904L 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 WP904L elbows are mandrel formed to ensure consistency. 904L 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 WP904L Bends are supplied as long radius return bends and short radius return bends. 904L 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. 904L 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. 904L 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.

Properties of AISI 904L Stainless Steel

904L SS Cold Forming

SS 904L is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.

904L SS Hot Forming

Working temperatures of 1652 – 2102°F (900 – 1150°C) are recommended for hot working processes. Do not work this SS below 1742°F (950°C). If the final forming temperature falls below this threshold, a solution anneal of 1976 – 2156°F (1080 – 1180°C) is necessary. Rapid quenching is required.

904L SS Machining

The cold work hardening rate of SS 904L makes it less machinable than 410. Low speeds and constant feeds will minimize this SS's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.

904L SS Welding

SS 904L can be readily welded by most standard processes. A post weld heat treatment is not necessary. All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 904L filler metal for best results.

904L SS Heat Treatment

904L stainless steel does not respond to heat treatment. Cold work will cause an increase in both hardness and strength. 1850-2050 F (1010-1121 C), followed by rapid cooling.
