TOUGH AND HARD SURFACING
DESCRIPTION
An electrode for components subjected to severe wear conditions.
The metal is crack and pore free and resistant to impact stress.
A buffer layer of Z-307HR electrodes is only required when welding difficult to weld steels.
APPLICATION
- Excavator parts.
- Dredger bucket blades.
- Gripper cogs.
- Percussion drill bits.
- Mining tools.
- Screw conveyors.
- Beaters.
- Demolition jaws and balls.
