High strength, hardenability, good toughness, small deformation in
quenching, high temperature creep strength and lasting
strength.It is used for manufacturing forgings with higher strength
and larger quenched and tempered cross section than 35CrMo steel,
such as big gear for locomotive traction, supercharger drive gear,
rear axle, connecting rod and spring clamp with great load, and
also for drilling pipe joint and fishing tool for oil deep Wells
below 2000m.
