Qu819 Rod – Laser Welding Wire Cold-Work Tooling 1.2767 / 1.2721 / 1.2714 – 46–48 HRC

Qu819 is the build-up wire for cold-work tooling and plastic moulds: EN ISO 14700 S Fe 3 · 819BS · filler no. ~1.6773.It matches the nickel-alloyed tool steels 1.2767 (X45NiCrMo4), 1.2721, the hammer steel 1.2714 (55NiCrMoV7) and 35NCD16 / 45NiCrMo18 / 60NiCrMo11. According to the datasheet its hallmark is the combination of high dimensional accuracy with high hardness and strength (46–48 HRC as welded) — exactly what a cavity or die needs when it is machined back to size after welding and then has to hold up in service.Recommended base materials1.2767 (X45NiCrMo4)1.27211.2714 (55NiCrMoV7) — hammer steel35NCD16, 45NiCrMo18, 60NiCrMo11 and similarTypical applicationsPlastic moulds — cavities and parting edgesCold-work toolingDies, cutting tools and hammer steelsParts that are machined back to size after weldingProperties and advantages46–48 HRC as welded — hardness without post-weld heat treatmentHigh dimensional accuracy per the datasheetRm max. 912 MPa, A 12–19 %Machining behaviour typical for the materialBobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.

QuCu81 is the ductile one of the three aluminium bronzes: EN ISO 24373 S Cu 6327 (CuAl8Ni2Fe2Mn2) · material no. 2.0922. At 140 HB it is the softest — in return it offers 30 % elongation, three times that of QuCu80.That toughness is the reason to choose it: in dissimilar joints between CuAl bronze and steel, and in joints between differing materials generally, the seam is under permanent stress because both sides expand differently. Ductile weld metal absorbs that; strong weld metal cracks. Equally suited to cladding on steel and cast iron. Sea-water and cavitation resistant, good sliding properties.Recommended base materialsCu-Al multi-component bronzesDissimilar joints CuAl bronze to steelCladding on cast iron and steelBuild-ups on tool steel and cast alloysTypical applicationsBronze-to-steel dissimilar jointsCladding welds on steel and cast ironJoint welds on CuAl bronzesSliding surfaces, sea water and cavitation loadProperties and advantagesA 30 % elongation — the most ductile weld metal of the range140 HB, Re 270 MPa · Rm 530 MPaSea-water and cavitation resistantGood sliding propertiesRod form advantage: Constant wire feed for manual cladding and dissimilar joints.Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,3 mm – 0,8 mm.

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 machinableRod form advantage: Constant wire feed for manual build-up welding, also on hard-to-reach contours inside the die.Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.
