The stainless steel square tube is superior in quality, hygienic and environmentally friendly, economical and practical. The thinning of the pipe and the development of a new reliable, simple and convenient connection method were successful. Heat treatment: bright solid solution under the protection of reducing gas, mechanical property analysis: the elongation Ψ strength δb, and hardness HRB (80~90) can be adjusted and controlled.
After the stainless steel square tube is corroded, the passivation treatment film on the surface is damaged, and the passivation treatment layer dissolves. Such as general corrosion: this kind of corrosion destroys most of the material uniformity of the surface, and the corrosion surface is relatively uniform. Where corrosion is reduced, corrosion of these species increases significantly. Such as residual welding metal oxides, powder layer from carbon steel grinding and polishing, etc.
Stainless steel square tube is widely used in construction engineering and daily life. There are mainly two types of product classifications for stainless steel square tube manufacturers: one is a relatively common way to classify square tubes according to the production process. Square tube manufacturers use four methods of hot rolling, cold drawing, extrusion and welding to produce square tubes.
Stainless steel square tube refers to a low-alloy structural steel that has a protective rust layer to resist gas corrosion and can be used to produce steel frames such as vehicles, road bridges, towers, and containers. Widely used in .. airlines, cars, engineering project production, cotton textile and boiler production, etc. The pointed square tube is a very common profile.
