Gautam Steel is a leading manufacturer and supplier of stainless steel 316 (1.4401), 316L (1.4404) and 316Ti (1.4571) grade buttweld pipe fittings and flanges. Gautam Steel offers a complete range of stainless steel 316/316L pipe fittings such as SS 316 reducer, SS 316 elbow, SS 316 tee, SS 316 cross, SS 316 end caps, SS 316 stub ends and SS 316 pipe bends. Stainless steel 316 and 316L 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 316 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 316 pipe fittings, SS 316 flanges and SS 316 pipe bends. Our specialty is to manufacture and supply large size fabricated 100% radiography tested SS 316 elbows, SS 316 reducers, SS 316 tees and SS 316 large diameter fabricated pipes.
Stainless steel 316 and 316L are the second most commonly used stainless steel grades after 304/304L, being a higher version of 304, with addition of molybdenum and slightly higher content of nickel. The properties of stainless steel 316 are similar to that of Type 304, except that alloy 316 is stronger at elevated temperatures.
316L is the low carbon version, while Type 316H is a higher carbon version of 316 stainless steels. Meanwhile, 316Ti is a titanium stabilized version of 316. Resistance to sensitization is achieved in type 316Ti with titanium additions to stabilize the structure against chromium carbide precipitation, which is the source of sensitization.
Gautam Steel 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.
