High Hardenability W Nr 1 7147 Alloy Structural Steel Material - China

High hardenability W-Nr.

1.7147: Performance analysis and industrial application guide

(Comply with DIN EN 10083-3 standard, alternative materials: 20CrMo5/25CrMo4) W-Nr.

1.7147 Excellent hardenability

- Jominy hardenability curve: hardness ≥HRC 50 at 10mm from the end face, ≥HRC 45 at 20mm

- Critical diameter (oil quenching): Φ40-60mm, suitable for uniform hardening of large-section parts W-Nr.

1.7147 Balance of strength and toughness

- Typical mechanical properties after quenching and tempering:

- Tensile strength 900-1100MPa

- Yield strength ≥700MPa

- Impact energy (-20℃) ≥40J W-Nr.

1.7147 Chemical composition and metallurgical control

| Elements | Standard range | Internal control accuracy | Performance impact |

|||||

| C | 0.17-0.22% | ±0.01% | Dominant factor of matrix strength and hardenability |

| Cr | 1.00-1.30% | ±0.05% | Improve corrosion resistance and hardenability |

| Mo | 0.15-0.25% | ±0.02% | Suppress temper brittleness and improve high temperature strength |

| Mn | 0.60-0.90% | ±0.03% | Solid solution strengthening and improved hot workability | Through precise composition design and process control, W-Nr.

1.7147 achieves the best balance between hardenability, strength and processability, and is particularly suitable for automotive, engineering machinery and other fields that require high-consistency mass production.

Our materials are certified by IATF 16949 and provide a full-process solution from bars to finished parts.
