904L Stainless Steel Pipe Fittings

Check Dimensions of ASTM A403 UNS N08904 Elbow, Tee and ASTM B366 WP904L Pipe Reducer

The 904L is an austenitic stainless steel and it has higher pitting and crevice corrosion compared to 316 and other lower alloys. As a 904L Stainless Steel Fittings Manufacturer we produce all kinds of fittings in this grade. This material also contains copper in its composition so that it is resistant to acids as well. The addition of copper in ASME SB366 Stainless Steel 904L Pipe Fittings makes them resistant against sulfuric acid in particular.

These fittings could be used in conjunction with other pipes and fittings of the same grade of other compatible grades. We produce different types of fittings. The buttweld fittings are special because they provide better friction at the connecting joints for better sealing. These Stainless Steel 904L Buttweld Fittings can also be welded with ease because of the additional buttweld at the connection. The ASTM B366 SS 904L Fittings can be used in heat exchangers, pollution control systems and in bleaching systems. The SS 904L Buttweld Elbow is used to change the direction of pipes. There are mostly two angles of elbows with 90 degrees and 50 degrees. The Werkstoff No 1.4539 904L Stainless Steel Tee is one of the commonly used type of fittings in this grade. Tee is used to divide the flow whereas the cap is used to end a connection. The Uns N08904 End Cap is a part of Stainless Steel 904L Buttweld Fittings. As a leading supplier, we produce all types of 904L Grade Steel Pipe Fitting products and our customers can get a list of products upon inquiry..
