QuFe23 Bobbin – Laser Welding Wire Hardfacing Hot-Work Steel 1.2343 / 1.2344 – 53–58 HRC

QuFe23 is the wear protection for hot-work tools: DIN EN 14700 S Fe 3 · DIN 8555 MSG 3-55 T · filler material no. 1.2343. The weld metal reaches 53–58 HRC and is designed for service temperatures up to 550 °C.The difference from a matching repair wire such as QuFe13: the point here is not to restore the base material but to apply a harder wear layer than the base material itself has. For multi-layer build-ups the datasheet explicitly calls for a buffer layer of QuFe65 or QuNi26 — without it the hard layer cracks.Recommended base materials1.2343, 1.2344, 1.2367, 1.26061.2311, 1.2312, 1.23581.2082, 1.2083, 1.28421.2764 – 1.2767For multi-layer build-ups, buffer with QuFe65 or QuNi26Typical applicationsHot shear bladesDiesDie-casting mouldsWear-resistant build-ups on hot-work tools up to 550 °CProperties and advantages53–58 HRC — depending on machining and welding layerWear-resistant at service temperatures up to 550 °CWeld metal highly polishable, temperable, nitridable, chrome-platable, CVD-coatableMachinable — reworkable despite the high hardnessRod form advantage: Constant wire feed for manual build-up welding on shear blade edges and dies.Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,3 mm – 0,8 mm.

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, machinableBobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.
