Product Description

1.7734 Alloy 15CDV6 Small Diameter Cold Drawn Seamless Aviation Tube—Product Overview

Material

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

Specification

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.

Chemical Composition

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:

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
