Product Details

EFS Melting 4140 QT Forged Solid Steel Rod Mould Steel

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.
