QuLPA-Stell6 Powder – Laser Cladding Powder Cobalt Base – Matching Stellite 6, 41 HRC
QuLPA-Stell6 Powder – Laser Cladding Powder Cobalt Base – Matching Stellite 6, 41 HRC
QuLPA-Stell6 is the cobalt-base cladding powder (CoCrW), matching Stellite 6 — the universal standard among cobalt hardfacing alloys.
The cobalt matrix retains its hardness even at high temperatures (hot hardness) and resists friction, corrosion, cavitation and erosion. Chromium (28.5 %) provides corrosion protection and chromium carbides, tungsten (4.4 %) strengthens the matrix. At 41 HRC Stellite 6 is the all-rounder: the best balance of wear resistance, toughness and heat resistance. The harder, more abrasion-resistant sister grade is QuLPA-Stell12 (44 HRC). Grain size 45–150 µm.
Recommended base materials
- universally applicable — steels, nickel and cobalt materials
- parts with wear, corrosion and heat combined
Typical applications
- valve seats and cones, sealing faces of fittings
- hot-forming tools, hot shears, extruder parts
- parts with high-temperature wear and cavitation
Properties and advantages
- Hot hardness — hardness retained at high temperatures
