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 materials1.4313 (X3CrNiMo13-4)1.4002, 1.4317, 1.4414Further 13 % Cr steels and cast steelTypical applicationsTurbine runners and hydropower componentsPump casings and impellersValves in 13 % Cr cast steelBuild-ups on unalloyed steels (watch dilution)Properties and advantagesStrong and tough at once — Re 600 · Rm 800 MPa · A 15 %Low carbon (C 0.03 %) via nickel alloying instead of carbonCorrosion resistance matching 13 % Cr(Ni) steels250 HBRod form: Rod lengths 1000 mm and 333 mm, Ø 0,3 mm – 0,8 mm.

QuFe18 is the martensitic 13 % Cr wire for general mechanical and plant engineering: AWS ER410 · ~1.4009.It is a hardenable material — it hardens as it cools. That is the decisive difference from the austenitic stainless wires: here you preheat and cool slowly rather than keeping things cold. In return you get a deposit that polishes and machines well and can afterwards be tempered to service hardness — the classic combination for valves, shafts, pump parts and sealing faces.Recommended base materials1.4000, 1.4006, 1.4008 — martensitic 13 % Cr steelsAISI 410, AISI 420 — the corresponding US gradesBuild-ups on 1.2083 and 1.2085Build-ups on unalloyed and low-alloy steels up to 450 °CTypical applicationsValves and sealing facesShafts and bearing seatsPump and turbine componentsRepairs on martensitic Cr steels in mechanical engineeringProperties and advantagesReadily polishable and machinable — the repair can be finished cleanlyCorrosion-resistant in water, gas and steamHardness as welded 150–225 HBWeld metal: Re 380 MPa · Rm 550 MPa · A 15 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.

QuMed4009 is a martensitic 13 % chromium steel to EN ISO 14343-A G/W 13 · AWS A5.9 ER410 (filler material no.: ~1.4009). Unlike the austenitic wires of the QuMed range, this weld metal hardens on cooling — it is a quench-and-temper material, not an austenite.The wire is intended for components that need corrosion resistance in water, gas and steam atmospheres, and for build-ups on unalloyed and low-alloy steels up to 450 °C.
