Introduction of A572 Gr 42 carbon steel plate sheet

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, A572 Gr 42 carbon steel plate sheet flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of A572 Gr 42 carbon steel plate sheet, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

The company cooperates with A572 Gr 42 carbon steel plate sheet steel plants such as Maanshan Iron and Steel, Youdan, Liugang, Tangshan Iron and Steel, Xinyu, Jinan Iron and Steel, Shougang, Shagang, Rizhao, Pinggang, Xicheng, Dachang and other steel mills all year round. Alloy plate, A572 Gr 42 carbon steel plate sheet boiler plate, container plate, carbon plate, open plate, I-beam, angle steel, channel steel, H-beam, round steel, steel pipe, hot rolled coil, cold rolled galvanized and other spot stocks.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A572 Gr 42 carbon steel plate sheet etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
