Structural seamless steel tube

        Length: The length of hot rolled (extruded, expanded) steel pipe is 3-12m, and the length of cold rolled (drawn) steel pipe is 2-10.5m

Carbon structural steel pipe (GB / 8162-2008)

        This type of structural steel pipe is generally smelted by converter or open hearth. The main raw material is molten iron plus scrap steel. The content of sulfur and phosphorus in steel is higher than that of high-quality carbon structural steel pipes. Generally, sulfur is ≤0.050% and phosphorus is ≤0.045%. The content of other alloy elements brought into the steel from raw materials, such as chromium, nickel, and copper generally does not exceed 0.30%. According to the composition and performance requirements, the grades of such structural steel pipes are Q195, Q215A, B, Q235A, B, C, D , Q255A, B, Q275 and other steel grades.

         This type of structural steel pipe has the largest output and is widely used. It is often rolled into plates, profiles (round, square, flat, work, grooves, angles, etc.) and profiles, and welded steel pipes. Mainly used in building structures such as factory buildings, bridges, ships and pipelines for general fluid transportation. Such steels are generally used directly without heat treatment.

Low-alloy high-strength structural steel pipe (GB / T8162-2008)

         In addition to a certain amount of silicon or manganese basic elements, such structural steel pipes also contain other elements suitable for China's resource situation. Such as vanadium (V), niobium (Nb), titanium (Ti), aluminum (Al), molybdenum (Mo), nitrogen (N), and rare earth (RE) and other trace elements. According to chemical composition and performance requirements, its grades are Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D, E, etc. The steel grade indicates that it has the same meaning as the carbon steel pipe.

         The ratio of this type of structural steel pipe to carbon structural steel. It has the advantages of high strength, good comprehensive performance, long service life, wide application range, and relatively economical. The steel is rolled into plates, profiles, seamless steel pipes, etc., and is widely used in bridges, ships, boilers, vehicles and important building structures.
