Properties and Applications

Basic type, high recovery (250%) hardfacing electrode for depositing primary and eutectic Cr, Nb, Mo, W and V-carbides in austenitic matrix. Suitable for hardfacing of parts subjected to heavy abrasion with moderate impact and service temperatures up to 600°C. Suitable for use in crushing and screening plants, sinter plant parts, wear bars and plates, scraper bars, blast furnace charging systems, cement furnaces, bucket teeth and lips. The typical transverse cracks occuring in such a hard metal is not suitable for applications where impact and shock conditions prevail. Wear coefficient of 1 layer deposit is 0,3% with SiO2. The weld metal is machinable only by grinding. It has a quiet and regular fusion. Weld with long arc length shall not be welded more then 4 layers. Possible to use with both DC and AC.
