GENERAL CHARACTERISTICS

CORODUR 64 is a highly C- Cr- B- W- V- alloyed flux-cored wire electrode that deposits a very hard martensitic micro structure with carbides. The deposit is resistant to strong mineral abrasion also at higher temperatures. This wire can be used for one layer welding without a big decrease of hardness. The decrease of hardness is approx. 10% at 400 °C and approx. 25% at 600 °C.

APPLICATION

Cement, mineral and brick industry, steel industry, refuse-incinerator plants, composting plants, mineral crushing, paddle wheels

GENERAL CHARACTERISTICS

CORODUR 67 is a high C- Cr- V- alloyed flux-cored wire electrode for extreme abrasive wear even at elevated temperatures. The fine grain structure of the weld deposit prevents a washout of the matrix and therefore the deposit has an extreme high scratch hardness. The thickness should not exceed two layers.

APPLICATION

Conveyor screws, fan blades, stirring devices, mixer paddles, cement and concrete pumps, slurry pumps, hot screening units, gravel and washing units, etc.

GENERAL CHARACTERISTICS

Very high C-, Cr-, B-alloyed flux-cored wire electrode for extreme hard and non-corrosive hardfacing against very high mineral wear also at high temperatures. The weld deposit has a ledeburitic structure, bearing many various hypereutectic carbides. A maximum deposit thickness of 6 mm (1-2 layers) is recommended. Hardness Reduction at 400°C app. 5%, at 600°C app. 10%.

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
