Description

Stainless Steel 304 Tubes, Seamless Tubes  & Welded Tubes Manufacturers in India-1.4301, UNS S30400 Stainless Steel Tubes 

Metline is a specialist manufacturer and supplier of 304 stainless steel tubes with Bright Annealing (BA Tube) or Polishing (Surface Roughness Ra 0.18). We produce 304 stainless steel tubes with outside diameter 6mm upto 5″, in wall thickness upto 10mm. Metline is a professional producer of both thin wall and thick wall stainless steel 304 tubes, with exports to over 70 countries across the globe. In addition to 304 stainless steel tubes, we can also produce and supply related tube fittings such as SS 304 ferrule fittings, SS 304 compression fittings, and SS 304 couplings and SS 304 valves.

Pipes are used to transport something, and tubes to construct something; hence, tubes are defined by the outside diameter and wall thickness (for construction stability), and pipes are measured by inside diameter to allow a calculation for transportation viz., speed, volumes, etc.

About 304 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.
