Both 35CrMo and 42CrMo steel are Chinese alloy steel materials. And they have high strength and toughness, good hardenability, and no obvious temper brittleness. Besides that, 35CrMo and 42CrMo steel usually do quenching and tempering treatment. After that, they have high fatigue limit and resistance to multiple impacts, and good low temperature impact toughness. But what is the difference between 35CrMo and 42CrMo steel? Below is about 35CrMo VS 42CrMo chemical composition.
35CrMo VS 42CrMo chemical composition:
| Grade | C | Si | Mn | Cr | Mo |
| 35CrMo | 0.32-0.40 | 0.17-0.37 | 0.40-0.70 | 0.80-1.10 | 0.15-0.25 |
| 42CrMo | 0.38-0.45 | 0.17-0.37 | 0.50-0.80 | 0.90-1.20 | 0.15-0.25 |
From the above 35CrMo VS 42CrMo chemical composition, we can find that there is tiny difference between 35CrMo and 42CrMo steel. The carbon content, Mn and Cr content of 42CrMo steel is little higher than that of 35CrMo steel. As a result, the 42CrMo steel strength is relatively higher than 35CrMo steel, and the 42CrMo steel price is also higher.
