TS EN 14700 E Fe15
DIN 8555 E 10-UM-65-GR

Properties and Applications

Basic type, high recovery (180%) electrode for depositing primary and eutectic Cr and Nb carbides in austenitic matrix. Suitable for hardfacing of parts, subjected to heavy abrasion with moderate impact. Service temperature is max. 450°C. The typical transverse cracks occuring in such a hard metal is not suitable for applications where impact and shock conditions prevail. Wear coefficient of one layer deposit is 0.5 % with SiO2. The weld metal is machinable only by grinding. Weld with long arc length and shall not be welded more than 2 layers. Possible to use with both DC and AC. 

Typical Applications: Suitable to use in hardfacing of cement crushers, cement presses and brick conveyor screws, mixer blades, press screws in oil industry, bucket lips and teeths in earth moving equipments.
