Mechanical Properties
Comparative mechanical properties across five related grades in different conditions:
| Grade / Condition | Tensile Strength (Rm, MPa) | Yield Strength (Rp0.2, MPa) | Elongation (%) | Hardness (HB) |
| 15CDV6 (1.7734.2 annealed) | — | — | — | ~197 HB |
| 15CDV6 (1.7734.4) | ≥ 700 | ≥ 550 | ≥ 13% | ~207 HB |
| 15CDV6 (1.7734.5) | 980–1180 | ≥ 790 | ≥ 11% | 293–352 HB |
| 15CDV6 (1.7734.6) | 1080–1250 | ≥ 930 | ≥ 10% | 321–363 HB |
| 1.7734 (annealed) | ≥ 898 | ≥ 228 | ~14% | ~443 HB |
Key Characteristics
-
High strength combined with toughness: Achieves tensile strengths in excess of 1,200 MPa (1.7734.6 condition) while maintaining ductility and structural integrity
-
Excellent weldability: Welding is feasible with minimal or no post‑weld heat treatment, preserving mechanical properties
-
Heat‑treatable: Response to quench and temper cycles allows tailored performance—e.g., austenizing ~980 °C followed by oil quench and tempering ~650 °C yields Rm 1175 MPa, Rp0.2 980 MPa, hardness ~39 HRC
