We specialise in the manufacture and supply of ASTM A403 WP304 Buttweld Pipe Fittings SS 304 pipe bends in both standard and non standard sizes, with bending radius of 1D, 1.5D, 3D upto 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.
