Features of automotive steel coil grade S500MC

40Cr alloy belongs to gb3077 "alloy structural steel". The carbon content of 40Cr steel is 0.37% ~ 0.44%, which is slightly lower than that of 45 steel. The content of Si and Mn is equivalent, and the content of Cr is 0.80% ~ 1.10%. In the case

40Cr alloy belongs to gb3077 "alloy structural steel". The carbon content of 40Cr steel is 0.37% ~ 0.44%, which is slightly lower than that of 45 steel. The content of Si and Mn is equivalent, and the content of Cr is 0.80% ~ 1.10%. In the case of hot rolling supply, the 1% Cr basically does not work, and their mechanical properties are roughly the same. Because the price of automotive steel coil grade S500MC is about half of that of 45 steel, 40Cr is not needed for the purpose of economy.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the automotive steel coil grade S500MC, alloy steel is very high, it is not easy to break and can be used for a long time.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the automotive steel coil grade S500MC product workpiece, thereby improving the production efficiency and production processing quality.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled automotive steel coil grade S500MC 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 automotive steel coil grade S500MC industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
