Carbon structure steel tube

 This kind of structural steel pipe is generally smelted by converter or open furnace, its main raw material is hot metal and scrap steel, the content of sulfur and phosphorus in steel is higher than that of high-quality carbon structural steel pipe, generally sulfur ≤0.050%, phosphorus ≤0.045%. The content of other alloying elements brought into the steel by raw materials, such as chromium, nickel and copper, is generally not more than 0.30%. According to the requirements of composition and performance, the grade of this kind of structural steel pipe is expressed by steel grade Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 and so on.

This kind of structure steel tube output is the largest, the use is very wide, many rolled into plate, profile (round, square, flat, work, slot, Angle, etc.) and profiles and manufacturing welding steel tube. It is mainly used in building structures such as workshop, bridge, ship and general pipeline for conveying fluid. This kind of steel is usually used directly without heat treatment.

Ratio of structural steel tube to carbon structural steel. It has the advantages of high strength, good comprehensive performance, long service life, wide application range and comparative economy. It is widely used in Bridges, ships, boilers, vehicles and important building structures.
