Advantages Of Din 1 7225 Steels Vs Carbon Material - China

1 - Material composition and performance characteristics

| Characteristics | DIN 1.7225 steels (42CrMo4) | Ordinary carbon steel (such as AISI 1045) |

||||

| **Main ingredients** | Contains Cr (0.9~1.2%), Mo (0.15~0.3%) | Mainly contains C (about 0.45%), no significant alloying elements |

| **Strength** | High strength (tensile strength can reach 900~1100 MPa) | Medium strength (tensile strength is about 500~600 MPa) |

| **Toughness** | Good (especially after quenching and tempering) | General (easy to fracture) |

| **Hardenability** | High (due to the presence of Cr and Mo, suitable for large cross-section parts) | Low (only suitable for small size parts) |

| **Fatigue resistance** | Excellent (suitable for dynamic loads) | General (easy to fail due to fatigue) |

| **Corrosion resistance** | Slightly better than carbon steel (Cr element provides some protection) | Poor (easy to rust) | 2 - Cost and processability

- **DIN 1.7225 steels**:

- **Higher cost** (due to alloying elements).

- **Slightly more difficult to process** (appropriate cutting parameters are required).

- **Ordinary carbon steel**:

- **Low cost**, easy to obtain.

- **Easy to process** (suitable for large quantities of simple parts).

Conclusion

Choose DIN 1.7225 steels (42CrMo4): suitable for high strength, fatigue resistance, large cross-section or dynamic load occasions (such as gears, shafts, aviation parts).

Choose ordinary carbon steel: suitable for low cost, low load, simple structural parts (such as brackets, non-critical connectors).
