The main varieties of hot-rolled steel plates are ordinary carbon steel, low alloy steel, container plate, weathering steel, pipeline steel, hot-rolled steel strip for automobiles, ship plate, gas cylinder steel, boiler and pressure vessel plate, A572 grade 42 ms steel coil. Hot-rolled steel strips are processed into different finishing lines to become steel plate, flat coil and slit steel strip products. Our hot-rolled steel plates are widely used in automobiles, machinery, ships, bridges, construction, pressure vessels, pipeline transportation, automotive industry.
Q345 is a steel material. It is a low alloy steel, with good comprehensive properties, low temperature properties, cold stamping properties, A572 grade 42 ms steel coil welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, A572 grade 42 ms steel coil steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.
The work performance of A572 grade 42 ms steel coil etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
