​
Mentioned below are C40 chemical composition and C40 mechanical properties:
C40 Chemical Composition
The Chemical Composition of C40 contains a low carbon content of 0.17 - 0.254 %. The material has an Mn content of 0.70 - 1.00 % which imparts hardness to the material. The contents of P is reduced to 0.035% and S is reduced to 0.035 % max as excess content of P and S can damage the quality of steel and can cause the carbon steel to break at low stresses. There is a Chromium, Nickel and Copper content of 0.25 % max.
