Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. A588 grade A structural steel plate, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous A588 grade A structural steel plate process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A588 grade A structural steel plate plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A588 grade A structural steel plate industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits.
