Alloy 15CDV6 (also designated WS 1.7734, AIR 9160C, 15CrMoV6) is a low‑carbon, chromium‑molybdenum‑vanadium heat‑treatable alloy steel. It combines high yield and tensile strength with excellent toughness and exceptional weldability, even without post-weld heat treatment
Designation: 15CDV6, WS 1.7734, AIR 9160C
Product Form: Cold-drawn, seamless, small-diameter precision tube
Applicable Standards: TE014 (seamless tube), AECMA FE‑PL1505, AIR 9160C, DIN series (65389/65390), ASNA 3108, LN 9369, etc.
Below is a comparative table featuring 15CDV6 and four similar grades (12CrMoV6‑9 / 1.7734, 14CrMoV6‑9 / 1.7735, 15CrMoV5‑9 / 1.8521, and 15CrMoV5‑10 / 1.7745) with their typical alloying ranges:
| Grade (Designation) | C (wt %) | Mn | Si (max) | P (max) | S (max) | Cr | Mo | V |
|---|---|---|---|---|---|---|---|---|
| 15CDV6 (AIR 9160) | 0.12–0.18 | 0.8–1.1 | ≤ 0.20 | ≤ 0.020 | ≤ 0.015 | 1.25–1.50 | 0.8–1.0 | 0.2–0.3 |
| 12CrMoV6‑9 (1.7734) | 0.12–0.18 | 0.8–1.1 | ≤ 0.20 | ≤ 0.020 | ≤ 0.015 | 1.25–1.50 | 0.8–1.0 | 0.2–0.3 |
| 14CrMoV6‑9 (1.7735) | 0.11–0.17 | 0.8–1.0 | ≤ 0.25 | ≤ 0.020 | ≤ 0.015 | 1.25–1.50 | 0.8–1.0 | 0.2–0.3 |
| 15CrMoV5‑9 (1.8521) | 0.13–0.18 | 0.8–1.1 | ≤ 0.40 | ≤ 0.025 | ≤ 0.030 | 1.20–1.50 | 0.8–1.1 | 0.2–0.3 |
| 15CrMoV5‑10 (1.7745) | 0.10–0.16 | 0.4–0.9 | 0.15–0.35 | ≤ 0.025 | ≤ 0.015 | 1.10–1.40 | 0.9–1.1 | 0.20–0.35 |
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 |
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
