• Nickel-based super-alloy flux-cored wire of the NiCrMoW type
• Particularly resistant to corrosion under oxidising and reducing atmospheres
• Weld metal is designed to withstand impact, compression, abrasion, oxidation, corrosion and heat up to 1100°C
• Excellent thermal shock resistance
• Can be machined without previous heat treatment
STELLOY C-O is suitable for welding of joints in steel clad with a nickel-chromium-molybdenum alloy and for the joining of nickel-chromium-molybdenum alloys to steel or to other nickel base alloys.
Base materials : UNS N 10002 ( ASTM B 334, B 336, B 366)
STELLOY C-O is also destined in general to surface all parts undergoing mechanical stress combined with corrosion, thermal shocks and/or high temperatures
Examples
Hot shear blades, lime kiln burner parts, dies, swages, press tools as well as pump parts, hot-piercing punches, rolling and wire-drawing guides, valves and reservoirs...
