Product Details

What is 202 stainless steel honing tube?

202 stainless steel honing tube is a high-precision steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation during cold bending, flaring, flattening and no cracks, etc., they are mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes. The chemical composition of honing steel pipe includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P and chromium Cr.

Advantages of honing:

1. Improve the surface roughness, and the roughness can basically reach Ra ≤ 0.08µ About m.
2. Correct roundness, ovality can be ≤ 0.01mm.
3. Improve surface hardness, eliminate stress deformation, and increase hardness HV ≥ 4 °
4. After machining, there is residual stress layer, which increases the fatigue strength by 30%.
5. Improve the fitting quality, reduce wear and prolong the service life of parts, but the processing cost of parts is reduced.

Honing process:

The honing steel pipe is processed by rolling. Because of the residual compressive stress on the surface layer, it is helpful to seal the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the generation or expansion of fatigue cracks can be delayed, thus improving the fatigue strength of the honing steel pipe. Through rolling forming, a cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the honing steel pipe inner wall, and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the fit property.
