34CrMo4 Chemical Composition
The Chemical Composition of 34CrMo4 contains a low carbon content of 0.14 - 0.19 %. The material has an Mn content of 0.4 - 0.6 % which imparts hardness to the material. The contents of P is reduced to 0.025% 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 alloys steel to break at low stresses. There is a high Chromium content of 1.4-1.7 % which adds additional yield and tensile on heat treatment.
