Description

Manufacturers & Suppliers of Stainless Steel 304L Seamless Pipes – 1.4306/1.4307 Seamless Pipes, UNS S30403 Seamless Pipes

Metline is a leading manufacturer and supplier of SS 304L seamless pipes. Our seamless 304L pipes are manufactured in a variety of size and schedule or thicknesses. However, there is a restriction on the manufacturing of large diameter pipe. Generally, seamless 304L pipes are available in stock in sizes upto 16″. Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless 304L stainless steel pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe.

About 304L Stainless Steel

Stainless steel 304(SS304) is the most basic stainless steel known as 18-8 grade with higher chromium and low carbon content. The low carbon content restricts carbide precipitation during welding as well as minimizes its susceptibility to intergranular corrosion. Stainless steel 304L (SS304L) is an extra low-carbon variation of SS304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. Both SS304 and SS304L have excellent resistance to a wide range of atmospheric, chemical and petrochemical, and food industry corrosions. Usually, they can be used in applications with the maximum temperature of 1650°F[900°C] exhibiting good oxidation resistance.
