Specifications And Uses Of Hot Rolled Steel Round Bars

Hot-rolled round steel is a technical term for metallurgy, a kind of round steel,Hot rolled steel round bars and belongs to steel for construction. Specification and use: The specification of hot-rolled round steel is 5.5-250mm. Among them,Hot rolled steel round bars small round steel of 5.5-25mm is mostly supplied in straight bundles, which are often used as steel bars,Hot rolled steel round bars bolts and various mechanical parts: hot-rolled larger than 25mm Round steel is mainly used for the manufacture of mechanical parts or seamless steel tube billets.

Performance transformation: It has the advantages of good hardenability, high hardness,Hot rolled steel round bars good wear resistance, and small heat treatment deformation. It is often used to make cold work molds that bear heavy loads,Hot rolled steel round bars large production batches, and complex shapes. However,Hot rolled steel round bars the Q345B low-alloy round steel is prone to problems such as high brittleness during use. Studies have shown that improving the morphology and distribution of carbides in Q345B low-alloy round steel can effectively improve material toughness.
