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 P295GH material standard plate should be derusted before cutting.

p295gh material standard, 07MnNiVDR, 07MnMoVR and 07MnNiMoDR quenched and tempered high strength steels adopt many new processes and technologies, such as multi-element microalloying treatment, liquid steel vacuum treatment, inclusion modification treatment, low speed and large reduction rolling and controlled rolling and cooling. They can meet the requirements of low welding crack sensitivity.

The toughness of steel such as p295gh material standard is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
