DIN 8555 MF 7-GF-200-KPR

Properties and Applications

Open-arc flux cored wire for the rebuilding and reclamation of heavy parts, made of carbon steels or 14% Mn steels. Due to it's high crack resistance, it is succesfully used for buffer layer application prior to hardfacing on crack sensitive parts. Weld metal is very resistant to pressure and impact. Machinable with carbide tipped tools.

Typical Applications: Rebuilding and reclamation of railway rails and crossovers, mill shaft drive end, buffer layer on gyratory crusher mantles, re-pointing of shovel teeth, buffer layer on crawler tractor link prior to overlaying with more abrasion resistance and crack sensitive materials, rebuilding of rollers made of low alloy steels.
