GENERAL CHARACTERISTICS
CORODUR 69 is a tubular wire for extreme abrasive wear, even at high temperatures up to 650°C. The deposit has a very fine ledeburitic structure, bearing a lot of different very hard carbides. CORODUR 69 is used, wherever abrasive wear is extremely high. It is also wear resistant at high temperatures up to 650 °C. Due to the high hardness pre heating of the base metal is recommended. The deposit should be subjected to little impact stress. The deposit is nearly free of slag; the weldability is excellent. Good results are already achieved by welding one layer. A maximum deposit thickness of 6 to 8 mm (2 layers) is recommended. The resulting deposits cannot be heattreated, machined or forged. Before overlaying on old previously hard-faced surfaces a buffering layer of CORODUR 200 K or 250 K is recommended.
APPLICATION
Concrete-industry, mixer parts, extruder, scrapers, sintering grates, mining
