Gautam Steel is a leading manufacturer and exporter of stainless steel 304 grade buttweld pipe fittings and flanges. Gautam Steel offers a complete range of stainless steel 304/304L pipe fittings such as SS 304 reducer, SS 304 elbow, SS 304 tee, SS 304 cross, SS 304 stub ends and SS 304 pipe bends. Stainless steel 304 and 304L 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 304 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 304 pipe fittings, 304 flanges and 304 pipe bends. Our specialty is to manufacture and supply large size fabricated 100% radiography tested 304 elbows, 304 reducers, and 304 tees.
Grade 304 is most commonly referred as the standard “18/8” stainless steel and is one of the most widely used stainless steel grade across the globe. 304H stainless steel offers higher strength compared to common grade 304, as it contains higher carbon content. The key benefits which 304H offers include higher heat resistant properties, tensile strength and creep strength.
Gautam Steel also stocks and supplies a complete range of SS 304 | 304L pipes to complement our existing production range of 304 buttweld fittings and flanges. Stainless steel 304 pipes can be supplied in cut to length sizes and also machined or fabricated to meet your piping requirements.
