AWS/ASME A 5.13 E Fe6
DIN 8555: E4-UM-60-ST
FEATURES & APPLICATIONS |
For repair and reclamation of high speed cutting and machining tools.
- High hardness tool steel electrode for high speed tool steels.
- Deposits maintain a very sharp edge.
- Alloying elements include tungsten, molybdenum and vanadium.
- Weld metal maintains many of its properties at elevated temperatures.
