The EN10025-5 S355J0WP steel plate surface hardening processing

Quenching of EN10025-5 S355J0WP steel plate is a heat treatment terminated in order to better develop the overall strength. But there are a lot of EN10025-5 S355J0WP steel plate used to produce machinery parts that only require hard surfaces and soft interiors. EN10025-5 S355J0WP steel plate will have this practical effect for the actual operation method, known as surface hardening.

The surface hardening of EN10025-5 S355J0WP steel plate has the following categories:

High frequency quenching: put the EN10025-5 S355J0WP steel plate into the high frequency electromagnetic coil and access to the high frequency current, then the product workpiece will cause the induced current. The high frequency current is only concentrated on the surface of the EN10025-5 S355J0WP steel plate, so if the surface of the EN10025-5 S355J0WP steel plate is heated. This method of heating and quenching is called high frequency electromagnetic induction heating quenching.

Flame quenching: it is the quenching method of flame termination heating with co2 and other vapor bodies.

Nitriding quenching: in order to reach the goal of only improving the carbon content of the surface of the EN10025-5 S355J0WP steel plate, the EN10025-5 S355J0WP steel plate is put into the nitriding agent to terminate the method of heating nitriding and quenching. In this kind of nitriding agent in the termination of heating, is the carbon element will penetrate into the surface of the EN10025-5 S355J0WP steel plate, only to make the surface of the EN10025-5 S355J0WP steel plate into high carbon steel.
