Stainless steel honing tube material: stainless steel honing tube 304, stainless steel honing tube 316, 316L, etc.

Scope of application: deep hole parts, oil cylinder cylinder, cylinder cylinder, plunger cylinder, etc.

Processing inner diameter: 20-1000mm, piston rod

Processing technology: Boring-honing. The specific definition of the surface heat treatment of stainless steel honing pipe is a metal heat treatment process that changes the surface properties by heating the surface of the steel part.

Characteristics of surface heat treatment:

1. Hardness

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

2. Wear resistance

The wear resistance and fatigue wear resistance of stainless steel honing pipe surface heat treatment under dry friction and sliding wear conditions are higher than those of ordinary heat-treated parts. This is due to the fine martensite grains in the structure, higher dispersion of piston rod carbides, and The combined result of higher compressive stress on the surface.

3. Fatigue strength

The surface heat treatment of stainless steel honing pipe can significantly improve the fatigue strength of the workpiece. For example, the automobile half-shaft made of 40MnB steel, the original process is the overall quenching and tempering, it is changed to quenching and tempering + surface heat treatment, and the service life is increased 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 it is widely used in various industries. Piston rods are inseparable from their characteristics.
