GTAW
- DISSIMILAR STEELS
Description
Rod for dissimilar welding.
GTAW rod for welding on dissimilar high carbon steels and nickel alloys. Also suitable for welding a wide range of high-temperature resistant nickel alloys with austenitic and ferritic steels. Mn and Nb are added to provide high resistance to hot cracking and tolerance to dilution when combined with ferrous alloys. Resistant to oxidation up to 900°C.
Specific welding/repair of furnaces, crucibles, and other high-temperature components.
