| Product List |
42crmo round steel has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and rupture strength at high temperature. It can be used to manufacture forgings with higher strength and larger quenched and tempered section than 35CrMo steel, such as large gear for locomotive traction, supercharger transmission gear, pressure vessel gear, rear axle, connecting rod and spring clamp with great load, and also can be used for drilling pipe joints and fishing tools for oil deep wells below 2000m, and can be used for bending machine dies, etc.
