SMA490BW steel coils sheet

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

SMA490BW steel coils,Structural steel for bridges is mainly used to make riveted and bolted welded bridge steel structures such as highway bridges, railway bridges, sea-crossing bridges, overpasses, viaducts, and large mechanical bridge cranes E grade bridge steel is suitable for low temperature and severe cold environment or bridge structural parts that are subjected to dynamic loads and the stress conditions of components are very complex and harsh,SMA490BW steel coils.

The corten plates offer high tensile, yield and mechanical strength at the elevated temperature These plates provide high toughness and harness at the high temperature and cryogenic temperature as well The application of corrosion Resistant Steel Plates is- these plates are used in the number of industries like landscape building, an automobile company, fertilizers, marine industry The plate is used in because of its good elasticity, ductility, thermal and electrical conductivity We follow all the industry-standard both national and international standards,SMA490BW steel coils.

SMA490BW steel coils,Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for 42CrMo steel is quenching and tempering.SMA490BW steel coils
