304L Stainless Steel Flanges

ASTM A182 F304L Pipe Flange and 304L Stainless Steel Flange Manufacturer in India

304L Stainless Steel Flanges are made up of 304L material. 304L material is similar to the 304 stainless steel but with a higher chromium and nickel content with a low carbon content. The low carbon content makes it less carbide precipitation forming during welding process. The Werkstoff No 1.4306 Stainless Steel Blind Flange produced by Great Steel & Metals is solution annealed and strengthened further.

PED Approved SS 304L Pipe Flange, DIN 1.4306 Slip On Flange & ASTM A182 F304L Flanges Manufacturer In India

There is range of flanges in the 304L material. Flanges are connectors used to connect two pipe ends or other fittings in a piping set up to hold them together. There are different shapes and standards of flanges. The SS 304L Weld Neck Flange manufactured by us for example is easy to weld with because of the neck. It has high grip for welding. The classes and standards nominate pressure ratings and the nominal sizes of the flanges. Our UNS S30403 Plate Flange is a plate with holes for bolts and nuts to hold them together. We produce flanges that could be tightened with bolts and nuts or be connected together with welding. The ANSI B16.5 Stainless Steel 304L Slip on Flange is another type used to connect two pipes together. This type of flange can let a pipe to slip on through it. It is used mostly with seamless pipes where the dimensions are kept precise. Great Steel & Metals also produces other types and shapes of flanges in all 304L Stainless Steel Flange Pressure Ratings. We can provide customized products upon request by customers.
