Description

CARBO DURIT Ni E x 5.0mm

Standards DIN 8555 G 21-GF-UM-50-CG

DIN EN 14700 E Ni20

Characteristics

CARBO DURIT Ni E is a tubular rod containing fused tungsten carbides in a nickel base matrix alloy. This alloy is especially designed for manual arc welding. The weld metal is composed of 60 to 65 % fused tungsten carbides which are embedded in a matrix alloy containing 35 to 40 % NiSiB.

CARBO DURIT Ni E is “unique” in that it produces a smooth, clean surface. The alloy flows extremely well, due to the low melting point of between 900 and 1000°C.

The nickel based matrix alloy provides excellent resistance to acids and other corrosive media.

CARBO DURIT Ni A is used for applications which are subject to extremely heavy abrasive wear and corrosive media at the same time.

Typical applications

Hardfacing equipment parts made of ferritic and austenitic steels.

mixer blades, milling plates, conveyor worms, stabilizer blades, slurry

pump valves, molding sand preparation plants , corrosion resistant

welded coatings on parts which are subject to strong abrasive wear, e.g. in the

chemical industry and the food industry.

Recommendations for best welding results

Thoroughly clean the welding zone. It should be exempt from grease, scale, corrosion, and similar contamination.

Preheat the work piece to 300 – 500° C.

During the welding process the local base material temperature has to be increased to 650°C, however, overheating should be avoided.
