| C | Si | Mn | P | S | Cr | Ni | Mo |
| 0.62~0.70 | 0.17~0.37 | 0.30~0.60 | ≤0.030 | ≤0.035 | 1.00~1.40 | 0.40~0.70 | 0.20~0.30 |
68CrNiMo steel plate has excellent physical properties, such as high strength, high hardness, high toughness, as well as good wear resistance and low temperature resistance. In low temperature environments of minus 30-50 degrees Celsius, the steel plate will not experience brittle cracking, ensuring its stability in extreme environments. In addition, the tensile strength of the steel plate should not be less than 1080 MPa, the yield strength should not be less than 835 MPa, and the elongation rate should not be less than 12%. These performance indicators have reached the international advanced level.
1. Aircraft engine components
2. Aircraft structural components
3. Automotive transmission system components
4. Key components such as transmission parts and crankshafts of large mechanical equipment
