Introduction
Hot rolled steel plates and strips (GB 2517-81) are commonly used for general structures. As most projects require steel of certain shape, size and strength, products such as hot rolled steel plates, strips and bars are all at hand for customers.
Hot rolled steel sheets and strips are produced by heating a steel slab to rolling temperature and then rolling it by a steel rolling machine. The result is a steel sheet or strip with good physical properties, such as mechanical strength, ductility, weldability and elongation, as well as good surface finish. Hot rolled sheets and strips are widely used in engineering structures, industrial equipment, and building construction.
Features and Advantages
The main advantages of hot rolled steel sheets and strips include excellent mechanical properties, better dimensional accuracy and control, honed surface finish, better weldability and formability, cost-effectiveness and low energy requirements.
The mechanical properties of hot rolled steel sheet and strips are largely attributable to their component chemistry and microstructure, such as grain size. The strength and ductility of hot rolled steel sheets and strips are significantly improved by elements such as arsenic and nitrogen. Furthermore, the grain size of hot rolled sheets and strips can be controlled by an appropriate thermo-mechanical processing, which helps maintain the desired qualities of the product.
Compared with cold rolled products, hot roll products have higher dimensional accuracy and superior surface finish. Hot rolled steel sheets and strips are produced with a more consistent and even thickness, providing better shape and dimensional accuracy.
Due to their excellent properties, hot rolled steel sheets and strips are found in a variety of applications. The automotive industry, for example, utilizes hot rolled sheet and strip for body panels, door components, engine parts and other automotive components. Hot rolled sheets and strips are also used in agricultural machinery, home appliances and steel containers.
Conclusion
Hot rolled steel sheets and strips have excellent mechanical and formability properties, superior dimensional accuracy and superior surface finish. Their excellent properties enable them to be used in various applications, such as body panels, automotive components, agricultural machinery, medical instruments and home appliances. With their cost-effectiveness, hot rolled steel plates and strips are an ideal option for general structures.
