S40C
Grade Introduction:
JISG4051 S40C steel, under JISG4051 standard, we can regard S40C carbon steel plate as high carbon steel.
S40C carbon steel is one mainly of high carbon steel, S40C has high strength and good machinability, cold plastic deformation of the 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, driveshaft, connecting rod, etc.
