A kind of stainless steel tube generally obtained by honing process is called stainless steel honing tube. One of the more commonly used is the honing gear, which is composed of the base body plus abrasive. It is used for honing, mainly to remove impurities and burrs on the surface of the material, so as to improve the surface finish. Stainless steel honing pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling treatment. Because there are no oxide layer on the surface of the honing tube, high pressure without leakage, high precision, high finish, no deformation during cold bending, flaring, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components.
