QuFe18 Bobbin – Laser Welding Wire 13 % Cr Steel / ER410 – Valves, Shafts, Pumps

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 %Rod form advantage: Ideal for manual build-up welding with constant wire feed — also in hard-to-reach areas.Rod form: Rod lengths 1000 mm and 333 mm, 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.

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.

QuFe11 is a build-up wire for hot-work tools: DIN EN 14700 S Fe 13, filler material no. 1.2367. The weld metal reaches 38–42 HRC and combines hot-wear resistance with toughness.That combination is the whole point of this wire: components exposed at elevated temperature to impact, pressure and abrasion at the same time need weld metal that is not merely hard but also yields without cracking. For a harder, more temper-resistant build-up, use its sibling QuFe12 (42–48 HRC).Recommended base materials1.2343, 1.2344 (X38CrMoV5-1 / X40CrMoV5-1)1.2367 (X38CrMoV5-3)1.26061.2764 – 1.2767Typical applicationsForging diesDie-casting moulds and plastic mouldsGuides and containers (extrusion)Continuous casting rollsProperties and advantages38–42 HRC — depending on machining and number of layersHot-wear resistant and tough — for impact, pressure and abrasion at elevated temperatureWeld metal can be hardened and tempered, nitrided, chrome-plated, CVD-coatedPolishable and machinableBobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.
