42CrMo Alloy Steel Plate Chemical Compositions

C ：0.38～0.45%
Si：0.17～0.37%
Mn：0.50～0.80%
S ：Allow residual content≤0.035%

Cr：0.90～1.20%
Ni：Allow residual content≤0.030%
Cu：Allow residual content≤0.030%
Mo：0.15～0.25%

The Main Features of 42CrMo Alloy Steel


The performance of 42CrMo Alloy Steel is close to 35CrMo. 42CrMo Alloy Steel Plate's strength and hardenability are better than 35CrMo due to the increase in carbon and chromium content. 42CrMo Alloy Steel Plate has a high fatigue strength and resistance to multiple impact capacity after quenched and tempered. Besides, its low temperature impact toughness is good, and it is no obvious tempering brittleness.
