AWS: None
EN 14700 E Fe 1
DIN 8555: E1-UM-250
FEATURES & APPLICATIONS |
For underlayments on carbon and low alloy steels, also as a stand alone overlay for medium hard tough build-ups on rails, shafts, etc.
- High build-up electrode depositing weldmetal that resists extreme compressive stresses.
- Very tough alloy for underlayments or medium hard tough overlays.
- Excellent machinability.
- Excels in vertical and horizontal position welding.
