According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.RD 40 shipbuilding marine grade steel plate

RD 40 shipbuilding marine grade steel plate,After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the steel plate should be derusted before cutting.
