JISG4051 S40C steel plate is High carbon alloy steel,S40C steel plate under JISG4051 specification, BBN Steel can regard S40C steel plate as high carbon alloy steel.S40C has high strength and good machinability, cold plastic deformation of medium, good weldability, after quenching and tempering after welding, heat treatment, no temper brittleness, but lower hardenability.
Bear the load for a small section of the larger pieces of quenched large normalizing or stress smaller parts and the Ministry of strength less demanding on the heart surface, hardening the surface wear parts, such as crankshafts, spindles, drive shaft, connecting rod, etc.
