Stainless steel square pipe tube

It has general corrosion resistance,It has high temperature oxidation resistance, but the oxidation rate will be affected by internal factors such as exposure environment and product morphology. The total heat transfer coefficient of metal depends on the thermal conductivity of metal, but also on other factors. Stainless steel keeps the surface clean, so it can conduct electricity. Metals with higher thermal conductivity have better heat dissipation than other metals

Product Parameter

Stainless square tube is a kind of hollow long round steel, which is widely used in industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, machinery and instruments, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture, kitchenware, etc.
