air cylinder tube
air cylinder tube description
Cylinder tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because there is no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on, it is mainly used for the production of pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless pipe. The chemical composition of the cylinder tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
air cylinder tube advantage
1、 improve the surface roughness, roughness can basically reach Ra≤0.08µ m or so. 2、correct roundness, ellipticity can be less than 0.01mm. 3、 improve the surface hardness, the force deformation is eliminated, hardness increase HV≥4° 4、after processing residual stress layer, improve the fatigue strength by 30%. 5、 improve the quality of fit, reduce wear, prolong the service life of parts, but the processing cost of parts is reduced.
