Qu7734 Bobbin – Laser Welding Wire 1.7734 / 15CDV6 – CrMoV Quenched & Tempered Steel (Aerospace)
Qu7734 is the laser welding wire for the special material 1.7734 / 15CDV6 — a heat-resistant, CrMoV-alloyed quenched and tempered steel used as an aerospace material in aviation, space, motorsport and defence. Welding rod / wire electrode for laser, MIG and TIG welding of chromium-molybdenum-vanadium quenched and tempered steels.
Its distinguishing feature is the combination of high strength and excellent weldability: unlike many high-strength quenched and tempered steels, 15CDV6 can be welded reliably and reaches a high tensile strength in the quenched and tempered condition. That is precisely why it is the material for rocket engines, extremely light and durable aircraft components and structures and motorsport chassis. 15CDV6 is the internationally used designation for 1.7734.
Recommended base materials
- 1.7734 / 15CDV6
- similar chromium-molybdenum-vanadium quenched and tempered steels
- high-strength, heat-resistant quenched and tempered aerospace steels
The wire is a matching filler — 15CDV6 components are welded with 15CDV6 filler.
Typical applications
- Rocket engines
- Extremely light and durable aircraft components and structures
- Parts for electric motors
- Motorsport chassis
- Components in the nuclear and defence industry
- Joint and repair welds on CrMoV quenched and tempered steels
Properties and advantages
- High strength with excellent weldability — the combination that makes 15CDV6 an aerospace material
- Weld metal: Rm 750 MPa
- Hardenable; high tensile strength in the quenched and tempered condition
- Heat-resistant, CrMoV-alloyed
- Low weight at high strength — ideal for lightweight construction
