Meltolit NI-WC
Flux cored wire filled with fused tungsten carbide and NiCrBSi- matrix for semi-automatic welding application. To protect surfaces against extreme abrasive wear in combination with corrosion attack...
Austenitic-ledeburitic structure. The hardest of the standard cobalt base alloys. Great resistance to corrosion, especially to reducing acids, impact, extreme wear and temperature shocks. Only machinable by grinding. Application: wear pads, rotary seal rings, pump sleeves; centre less grinder work rests, etc. Tensile strength: 630 N/mm2 Hardness: 55 HRc (20°C), 44 HRc (600°C), 34 HRc (bei 800°C)
