DM Special Steel Ltd is a leading manufacturer and supplier of stainless steel 310S (1.4845), 310 (1.4841) buttweld pipe fittings and flanges. DM Special Steel Ltd offers a complete range of stainless steel 310S pipe fittings such as SS 310S reducer, SS 310S elbow, SS 310S tee, SS 310S cross, SS 310S end caps, SS 310S stub ends and SS 310S pipe bends. Stainless steel 310S pipe fittings are manufactured in compliance with ASTM A-403 and ANSI B16.9 / 16.28/ MSS SP-43 / Welding Bevel Standards ANSI B 16.25.
We specialise in the manufacture and supply of SS 310S pipe bends in both standard and non standard sizes, with bending radius of 1D to 10D or any other custom bending radius. We offer ex-stock delivery of various standard size and type SS 310S pipe fittings, SS 310S flanges and SS 310S pipe bends. Our specialty is to manufacture and supply large size fabricated 100% radiography tested SS 310S elbows, SS 310S reducers, SS 310S tees and SS 310S large diameter fabricated pipes.
Commonly referred to as UNS S31008, stainless steel 310S grade is generally used in elevated temperature applications. Due to its high chromium and nickel content, the general corrosion resistance of 310S is more superior to 304 or 309 in most environments. Stainless steel 310S is mostly similar to grade 309, but offers greater corrosion resistance and oxidation at high temperatures. As compared to Type 310, Type 310S stainless steel is identical to it except for a lower carbon content that minimizes carbide precipitation and improves weldability.
DM Special Steel Ltd also stocks and supplies a complete range of SS 316 | 316L pipes to complement our existing production range of SS 316 buttweld fittings and SS 316 flanges. Stainless steel 316/316L pipes can be supplied in cut to length sizes and also machined or fabricated to meet your custom piping requirements.
