4140 alloy steel plate advantage
4140 alloy steel plate has good machinability, processing deformation is small, fatigue resistance is quite good, and so on hardenability steel,4140 heat treatment after good strength and good comprehensive mechanical properties, good technology, high yield. The highest use temperature is 427 ℃.4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature. It is used for manufacturing forgings requiring higher strength and larger conditioning section than 35CrMo steel, such as large gear for locomotive traction, turbocharger transmission gear, rear shaft, connecting rod and spring clamp with great load, and can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m, and can be used for bending machine mold, etc.
