First, the thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, its processing cost will increase significantly; second, the process of the product determines its limited performance, generally The precision of seamless steel pipe is low: the wall thickness is uneven, the brightness of the inner and outer surfaces of the pipe is low, the cost of cutting to length is high, and there are pits and black spots on the inner and outer surfaces that are not easy to remove; third, its detection and shaping must be processed offline. Therefore, it embodies its superiority in terms of high pressure, high strength, and mechanical structural materials.

Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles of straight strips, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used for manufacturing mechanical parts and tube blanks of seamless steel pipes wait.
