Basic-graphite coated high-performance electrode with 180% yield for welding highly wear-resistant deposits. Weld metal made of special carbide containing chromium-boron hard alloy.

Most important fields of application
Highly wear- and abrasion-resistant coatings on components made of unalloyed and alloyed steels which are exposed to extremely high abrasive wear caused by sand, gravel, ore, coal, cement, slag. Due to its high abrasion resistance at elevated temperatures, it is particularly suitable for applications on crushing plants for red-hot coal, coke, slag.

Special notes
Weld metal can only be machined by grinding. Clear weld pool medium high build-up weld beads. High current carrying capacity. Do not apply more than 2 layers on top of each other. MT-Dur 68 deposits an almost slag-free weld metal when flowed correctly.

Re-drying
Generally not necessary. However, the coating can withstand re-drying up to + 150°C
