QuLPA-Ni24 is the nickel-base cladding powder for matching build-ups on Inconel 625 / 2.4856 and similar nickel-base materials (NiCr22Mo9Nb).Its microstructure is austenitic and non-transformable — hence the unusual span: high strength and toughness up to 1100 °C and at the same time toughness down to −196 °C. Molybdenum and niobium in the NiCr matrix give, per the datasheet, exceptional fatigue strength, plus favourable long-term creep values and resistance to stress and hot cracking. Hence its use in aerospace and the chemical industry. At 17 HRC the deposit is soft — it delivers corrosion and temperature resistance, not hardness.Recommended base materials2.4856 — Inconel 625 / Alloy 6252.4858 — Alloy 8251.4539 (904L), 1.4529, 1.4876 (Alloy 800)ISO 20172: NiCr22Mo9Nb with group 1.1 / 1.2Typical applicationsAerospaceChemical industryComponents up to 1100 °C and cryogenic use down to −196 °CCorrosion protection cladding by laser metal deposition (LMD)Properties and advantagesStrong and tough up to 1100 °C, tough down to −196 °CResistant to stress and hot crackingExceptional fatigue strength thanks to Mo and Nb17 HRC (15–19 HRC).
