CORODUR 70 is a highly alloyed flux cored wire. Due to this high alloy content, parts of industry that experience extreme sliding abrasion from fine minerals can be protected and rebuilt with excellent results. The properties of the wire remains after multi-layer welding even during higher working temperatures.

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.
