QuFe12 TIG Welding Wire – Hot-Work Steel 1.2343 / 1.2344 – 42–48 HRC, temper-resistant

QuFe12 is the hard, temper-resistant build-up wire for hot-work tools: EN 14700 S Fe 3 · DIN 8555 M/WSG3-Gz-45-T, filler material no. 1.2567. The weld metal reaches 42–48 HRC.The 4 % tungsten content is the defining feature: it gives the weld metal excellent temper resistance — the hardness survives when the tool heats up again in service. The microstructure of the un-annealed weld metal is martensitic with retained austenite and carbides.

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 machinableTIG advantage: For larger build-up areas where laser fine welding would be too slow.

QuFe21 is a high wear-resistance hardfacing wire to DIN EN 14700 S Fe 6 for tools exposed to heavy abrasion and pressure under moderate impact loads and elevated service temperatures — typically slide faces, guideways and sealing edges. Achievable hardness: 53–58 HRC. Particularly good abrasion behaviour with glass-fibre-reinforced plastics.Uncoated. QuFe21 is the uncoated version. Material, hardness and application are identical to the copper-coated variant QuFe20 — only the copper layer is missing. If the extra protection against rust matters for longer storage or humid workshop conditions, QuFe20 is the one to choose.Recommended base materials1.2082, 1.2083 — plastic mould steels1.2311, 1.2312 — quenched and tempered mould steels1.2343, 1.2344, 1.2367 — hot-work tool steels1.2606, 1.2764, 1.2765, 1.2842 — other tool steelsNote: For multi-layer build-up, apply a buffer layer using QuFe65 or QuNi26.Typical applicationsSlide faces and sliding areas on toolsGuideways in tool and mould makingSealing edges and parting linesWear protection on moulds for glass-fibre-reinforced plasticsBuild-up welding on parts under abrasion, pressure and elevated temperatureProperties and advantagesAchievable hardness 53–58 HRC — depending on machining and weld layerHigh wear resistance against abrasion combined with pressureDesigned for elevated service temperaturesGood abrasion behaviour with glass-fibre-reinforced plasticsPost-processing: excellent polishability, hardenable, nitridable, chrome-platable, CVD-coatable, machinableTIG advantage: For large-area wear build-up away from the laser — Ø 1.0–1.2 mm, considerably higher deposition per layer.TIG form: for manual repair welding.
