E1–UM–300
DIN 8555 :EF1
EN 14700 :Application/properties:
Thick basic-covered electrode is suitable for wear-resistant layer on medium-hard parts. The weld metal has relatively good machinability or chip removal properties. The weld metal is resistant to cracking and porosity. This electrode is suitable for welding parts subject to impact sliding wear.
