Introduction

It has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and rupture
strength at high temperature. It is used to manufacture forgings with higher strength and larger quenched and tempered cross
section than 35CrMo steel, such as big gear for locomotive traction, transmission gear for supercharger, rear axle, connecting rod
and spring clamp with great load, and it can also be used for drill pipe joint and fishing tool in oil deep well below 2000m
