Stainless steel honing steel pipe 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.
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.
