QuLPA-Fe44 Powder – Laser Cladding Powder Stainless 1.4404 / 316L (ER316L) – Austenitic, Corrosion Resistant

QuFe52 is the classic wire for dissimilar (black-and-white) joints: EN ISO 14343-A W/G 23 12 L Si · AWS A5.9 ER309LSi · filler material no. 1.4332.Its high alloy content (Cr 23 % / Ni 13.5 %) is not an end in itself: it is the reserve that gets diluted when the carbon steel melts in. A regular 18/8 wire would lose its austenitic safety margin here and harden — ER309LSi keeps its microstructure. That is why it is the standard for cladding on unalloyed and low-alloy backing steels and for joining stainless to carbon steel. Low-carbon (C 0.02 %) and therefore resistant to intergranular corrosion, usable up to 350 °C.Recommended base materials1.4306, 1.4401, 1.44041.4541, 1.4550, 1.4571, 1.4580each in combination with carbon steelsCladding on unalloyed and low-alloy backing steelsTypical applicationsDissimilar joints — stainless to carbon steelCladding welds on backing steelsChemical plant and vessel construction up to 350 °CBuffer layer beneath matching stainless cap passesProperties and advantagesCr 23 % / Ni 13.5 % — alloy reserve against dilution by the carbon steelLow-carbon (C 0.02 %) → resistant to intergranular corrosionUsable up to 350 °C (wet corrosion)Weld metal: Re 430 MPa · Rm 600 MPa · A 31 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,6 mm.

QuLPA-Fe13 is the laser cladding powder for highly wear-resistant build-ups on tools exposed to heavy abrasion and pressure with moderate impact loading and elevated operating temperatures — per the datasheet typically slide faces, guideways and sealing edges.It is a wear layer, not a matching repair material: it is deposited on the hot-work and plastic mould steels 1.2343 / 1.2344 / 1.2311 / 1.2312 / 1.2083 and similar. Approx. 42 HRC (40–44 HRC as deposited). Where more hardness is needed, QuLPA-Fe20 (51–55 HRC) is the next step.Recommended base materials1.2343, 1.2344, 1.2367 — hot-work tool steels1.2311, 1.2312 — plastic mould steels1.2082, 1.2083, 1.2606, 1.28421.2764, 1.2767Typical applicationsSlide faces and guidewaysSealing edgesTools subject to abrasion and pressure at elevated temperatureArea cladding by laser metal deposition (LMD)Properties and advantagesApprox. 42 HRC (40–44 HRC as deposited)Very good polishing, tempering, nitriding, chrome plating behaviourCVD-coatable and machinableGrain size 45–150 µmPowder form: grain size 45 - 150 µm — for laser metal deposition (LMD).

QuLPA-Fe18 is the cladding powder made of martensitic 13 % Cr steel: ~EN ISO 14343-A G/W (13) · ~AWS A5.9 ER420 · material no. ~1.4028.It is intended for build-ups on structural parts in water, gas and steam atmospheres — wherever corrosion resistance is required alongside wear protection. Base materials are the 13 % martensitic Cr steels 1.4000–1.4006 / AISI 410 / AISI 420. On unalloyed and low-alloy steels it can be used up to 450 °C. The deposit polishes well, 55 HRC.Recommended base materials1.4000 – 1.4006 — martensitic 13 % Cr steelsAISI 410, AISI 420Build-ups on steels such as 1.2083, 1.2085Unalloyed and low-alloy steels up to 450 °CTypical applicationsStructural parts in water, gas and steam atmospheresComponents needing wear protection and corrosion resistance at oncePolished functional surfacesArea cladding by laser metal deposition (LMD)Properties and advantages55 HRC as depositedCorrosion resistant — 13 % chromiumGood polishing and machining behaviourGrain size 45–90 µmPowder form: for laser metal deposition (LMD).

QuLPA-Fe20 is the hard grade among quada's cladding powders: 51–55 HRC as deposited, against approx. 42 HRC for QuLPA-Fe13. Same field of use — slide faces, guideways, sealing edges — but for higher abrasion.The point the datasheet singles out: good abrasion behaviour with glass-fibre reinforced plastics. That is exactly where moulds wear fastest, because the glass fibres act like abrasive. Higher chromium and vanadium (5.2 % Cr, 0.9 % V) carry the hardness.Recommended base materials1.2343, 1.2344, 1.2367 — hot-work tool steels1.2311, 1.2312 — plastic mould steels1.2082, 1.2083, 1.2606, 1.28421.2764, 1.2767Typical applicationsMoulds for glass-fibre reinforced plasticsSlide faces, guideways, sealing edgesTools with heavy abrasion at elevated operating temperatureArea cladding by laser metal deposition (LMD)Properties and advantages51–55 HRC as depositedGood abrasion behaviour with GFRP per the datasheetPolishable, temperable, nitridable, chrome-platable and CVD-coatableGrain size 53–150 µmPowder form: grain size 53 - 150 µm — for laser metal deposition (LMD).

QuLPA-Fe20 60/40 is the lower-alloyed variant of QuLPA-Fe20. Field of use and post-processing are identical — slide faces, guideways, sealing edges, good abrasion behaviour with glass-fibre reinforced plastics.The difference is in the analysis: 3.5 % Cr instead of 5.2 %, 0.23 % C instead of 0.32 %. The result is a slightly lower hardness of approx. 51 HRC (49–53 HRC as deposited) at a finer grain size (45–150 µm instead of 53–150 µm). Where full hardness is required, QuLPA-Fe20 (51–55 HRC) is the choice.Recommended base materials1.2343, 1.2344, 1.2367 — hot-work tool steels1.2311, 1.2312 — plastic mould steels1.2082, 1.2083, 1.2606, 1.28421.2764, 1.2767Typical applicationsSlide faces, guideways, sealing edgesMoulds for glass-fibre reinforced plasticsFiner deposit geometries thanks to 45–150 µm grainArea cladding by laser metal deposition (LMD)Properties and advantagesApprox. 51 HRC (49–53 HRC as deposited)Finer grain size 45–150 µmPolishable, temperable, nitridable, chrome-platable and CVD-coatableGood abrasion behaviour with GFRPPowder form: grain size 45 - 150 µm — for laser metal deposition (LMD).

QuLPA-Fe10Cr is the laser cladding powder for heavily loaded mould cavities. It matches the quenched and tempered plastic mould steels 1.2311, 1.2312, 1.2162, 1.2738, 1.2764 and 1.2767 as well as the CrMo grades 42CrMo4 / AISI 4140.What makes this powder usable in mould making is its post-processing behaviour: per the datasheet the deposit is EDM-machinable, texturable, polishable, chrome-platable, etchable, nitridable, temperable and hardenable — the repaired cavity can be treated exactly like the base material. 27–38 HRC.Recommended base materials1.2311, 1.2312, 1.2738 — plastic mould steels1.2162, 1.2764, 1.276742CrMo4 / AISI 4140, 25CrMo4, AISI 413013CrMo 4 4, GS-17 CrMo5 5Typical applicationsModifications and repairs on mould cavitiesHeavily loaded plastic mouldsArea cladding by laser metal deposition (LMD)Parts that are subsequently EDM-machined, etched or texturedProperties and advantages27–38 HRC as depositedEDM-machinable, etchable, texturable — photo-etching and graining possiblePolishable, chrome-platable, nitridable, temperable and hardenableGrain size 45–90 µmPowder form: grain size 45 - 90 µm — for laser metal deposition (LMD).
