Carbon Steel Pipe Q345B ST52 Cold Drawn Honed Cylinder Steel Tube Carbon Pipe
Carbon Steel Pipe Q345B ST52 Cold Drawn Honed Cylinder Steel Tube Carbon Pipe
Product description
Honing the cylinder pipe
The surface quality is good, the surface is cross mesh, which is conducive to the storage of lubricating oil and the maintenance of oil film. It has a higher surface support ratio (the actual contact area of the hole and the shaft and the ratio of the matching area between the two), so it can bear larger load and wear resistance, thus improving the service life of the product.
