FEATURES & APPLICATIONS |
Due to exceptional strength and crack resistance, it is ideal for repairing tools, dies, spring steel and any dissimilar metal combinations, except for the aluminum and copper alloys. It is also recommended for repairing worn parts and as an underlay for hardfacing.
- Special vertical position high strength electrode for dissimilar steels.
- Unique “Fast-Freeze” coating simplifies vertical down and up welding.
- Ideal for poor fit up joints in all positions.
- Controlled weld puddle allows for filling holes and joining dissimilar steels.
