Stainless steel square pipe tube
It has general corrosion resistance similar to unstable ni-cr304. 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

Description
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.

It is used in heavy industry and light industry, Daily necessities industry and architectural decoration industries.
Product features
| Surface finish | Characteristics & Application |
| NO.1 | Hot-rolled surface, annealed and pickled, can be used as cold-rolling material, industrial tanks and chemical devices. |
| NO.2D | Cold-rolled, annealed and pick led with out skin passing the dull products can be used as auto mo bile parts, building materials and piping. |
| NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surface treatment to improve its chemical properties, NO.2B. could nearly satisfy comprehensive uses. |
| NO.3 | Polished with abrasive belt of grit #100#120, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
| NO.4 | Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3. are used as bathtub building inner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-320 on the No.4.finish and has continuous streaks, mainly used as building ornaments, elevators, door of building, frontal plate etc. |
