Difference between precision and hardness of hot-rolled and

Oct 15, 2018 · Cold drawn seamless steel pipe is a kind of high precision precision cold drawn seamless steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of the precision cold-drawn seamless steel pipe have no oxide layer, high pressure, no leakage, high precision, high smoothness, no cold deformation, no flaring, no cracking, no cracks, etc., so it is mainly used to produce pneumatic or hydraulic components. Such as cylinders or cylinders, can be seamless tubes. 1.
