CLASSIFICATION

EN 14700: TNi2
DIN 8555¹: MSG 23-GF-200/350-CKNTZ

¹ Former classification replaced by EN 14700

DESCRIPTION

• Cobalt hardened super-alloy metal-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

APPLICATIONS

STELLOY CCo-G is suitable for surfacing parts undergoing oxidation, corrosion and mechanical stresses at high temperature

Examples
Tube extrusion mandrels, hot shearing blades, extrusion tooling, forging dies.
