Qu4351 Bobbin – Laser Welding Wire 13/4 / ER410NiMo (1.4351) – Turbines, Pumps, Hydropower
Qu4351 is the 13/4 wire: DIN EN ISO 14343-A G/W 13 4 · AWS ER410NiMo · ISO 14343-B SS410NiMo · filler no. 1.4351. Cr 13 % · Ni 4 % · Mo 0.5 %.
The nickel is what sets it apart from plain ER410: it keeps the structure martensitic without having to raise the carbon (only 0.03 % C). The result is a weld metal that is strong (Re 600 / Rm 800 MPa) and yet stays tough (A 15 %) — the combination that turbine runners, pump casings and hydropower components in 1.4313 / 1.4317 demand. Also for build-ups on unalloyed steels; watch the dilution.
Recommended base materials
- 1.4313 (X3CrNiMo13-4)
- 1.4002, 1.4317, 1.4414
- Further 13 % Cr steels and cast steel
Typical applications
- Turbine runners and hydropower components
- Pump casings and impellers
- Valves in 13 % Cr cast steel
- Build-ups on unalloyed steels (watch dilution)
Properties and advantages
- Strong and tough at once — Re 600 · Rm 800 MPa · A 15 %
- Low carbon (C 0.03 %) via nickel alloying instead of carbon
- Corrosion resistance matching 13 % Cr(Ni) steels
- 250 HB
Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,3 mm – 0,8 mm.
