Production Flow

The specific definition of surface heat treatment is the metal heat treatment process that changes the surface properties by heating and cooling the surface of the steel. Then, do you know the characteristics of surface heat treatment?

1, hardness

The heat treatment hardness of the high frequency induction surface is 2HRC~3HRC higher than that of the ordinary furnace.

2, wear resistance

The wear resistance and fatigue wear resistance of surface heat treatment under dry friction, the sliding wear are higher than those of ordinary heat treated parts due to fine martensite grains, high carbide dispersion and high compressive stress on the surface.

3, fatigue strength

Surface heat treatment can significantly improve the fatigue strength of the workpiece. For example, the automobile semi-axle made of 40MnB steel, the original process is the overall quenching and tempering, changed to quenching and tempering + surface heat treatment, the life is improved by nearly 20 times. In addition, the surface heat treatment reduces the notch sensitivity of the parts. Surface heat treatment is to improve the characteristics of the product, and is widely used in various industries, which are inseparable from its characteristics.
