Small Diameter Thin Wall Stainless Steel Tube 300 And 400 Series Austentic
zheheng steel is a one of the important suppliers of stainless steel pipes,tubes, alloy pipes, small diameter stainless steel tube ,thin wall stainless steel tube and stainless steel pipes in China.Our company has strong technical force,producing and inspecting goods according to ASTM,JIS,BS,EN,GOST and DIN standard strictly,which greatly improves product quality. We have the capacity and experience to meet different customers' requests. Our goal is to supply quality products with the best services and satisfy the requirements of clients from at home and abroad.
Due to the austenitic structure of the 300 series stainless steel tube, it has strong corrosion resistance in many environments, has good resistance to fracture caused by corrosion caused by metal super stress, and its material properties are not heat treated. Impact. 300 series stainless steel tube is an alloy material containing iron, carbon, nickel and chromium, a non-magnetic stainless steel tube material, which has better forgeability than 400 series stainless steel tube.
Stainless steel tubes have excellent corrosion resistance, formability and toughness over a wide temperature range, so they are widely used in heavy industry, light industry, household goods industry and architectural decoration industries, but in different environments. It is important to choose a different stainless steel tube variety.
