CORODUR® 68

CLASSIFICATION

DIN 8555 | DIN EN 14700
MF 10-70-CGZ | T Fe 15-70-CGZ

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%.

CORODUR® 67

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Fe16 | MF 10-65-GZ

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.

CORODUR® 65

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Fe16 | MF 10-65-GZ

GENERAL CHARACTERISTICS

CORODUR 65 is a highly C- Cr- Mo- Nb- W- V- alloyed flux-cored wire electrode, which forms extremely hard carbides. This is used for hardfacing to extremely strong abrasive mineral wear. The deposit retains its wear resistance up to 800°C. The structure consists of primarily and eutectic solidifying Cr- carbides plus Nb- Mo- W- V- carbides. The hardness reduction at a temperature of 400°C is approximately 4% and at 700°C approximately 10 %. This wire is recommended for use in sintering plants, augers and blast furnace bells.

APPLICATION

parts in hot screening units, grates, sinterbreaker

Datasheet

CORODUR® 64

CLASSIFICATION

DIN EN 14700 | DIN 8555
T Fe16 | MF 10-65-GZ

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
