Honed pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to its features such as oxide-free inner and outer walls, pressure resistance without leakage, high precision, high brightness, cold bending without deformation, and no cracks upon expansion or flattening, it is mainly used to produce products like pneumatic or hydraulic components, such as cylinders, which can be seamless pipes. The chemical composition of honed pipe includes carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P), and chromium (Cr).
