As an important industrial material, stainless steel round tubes have been widely used in many fields due to their unique material and process characteristics. The following are the main features of stainless steel round tubes:
Material and surface treatment: Stainless steel round tubes are usually made of stainless steel materials such as 304, 316 and 321, which have excellent mechanical properties and corrosion resistance. In addition, stainless steel round tubes are also surface treated, such as pickling and polishing, to make their surfaces smoother, brighter and more beautiful.
Mechanical properties: Stainless steel round tubes have excellent mechanical properties, high strength and good ductility. This makes it have excellent performance in terms of pressure resistance and deformation resistance. At the same time, stainless steel round tubes also have good impact resistance and can remain stable under high-intensity working conditions.
Corrosion resistance: Stainless steel round tubes have good corrosion resistance and are particularly suitable for humid and corrosive environments. Stainless steel materials can prevent corrosion and blockage inside the pipeline and ensure smooth transportation of fluids. In addition, stainless steel round tubes can maintain stable chemical properties under high temperature and acidic and alkaline environments without corrosion and oxidation.
Processing performance: Stainless steel round tubes have good processing performance and can withstand various complex shape requirements. This allows stainless steel round tubes to be processed through different processes such as cold drawing, cold rolling, welding and hot rolling to meet different usage requirements.
Environmental protection and safety: Stainless steel round tube products are safe, hygienic and reliable, and there is no need to worry about the occurrence of red water, green water and other phenomena. At the same time, it has good impact resistance, and there is no need to worry about the impact caused by the reduction of the inner diameter or the increase of resistance caused by the common rust protrusions in the galvanized steel pipe.

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and
mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
