GB/T8162 Seamless Steel Pipe Description

GB/T8162 is a standard seamless pipe, suitable for seamless pipes in general structures and mechanical structures. The parts after quenching and tempering of GB/T8162 seamless  steel pipe have good comprehensive mechanical properties and are widely  used in various important structural parts, especially those connecting  rods, bolts, gears and shafts that work under alternating loads.  However, the surface hardness is low and not wear-resistant. Quenching  and tempering, as well as surface quenching can be used to improve the  surface hardness of the parts.
