The advantages and application of EN 10025-4 S420ML pdf

The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, EN 10025-4 S420ML pdf is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of EN 10025-4 S420ML pdf, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.
