GTAW
- DISSIMILAR STEELS
Description
Rod for dissimilar welds.
GTAW rod for welding on dissimilar, high-carbon steels and nickel alloys. Suitable also for welding a wide range of Nickel alloys resistant to high temperature between themselves and with austenitic and ferritic steels. Mn and Nb are added in order to give high resistance to hot cracking and tolerance to dilution by combination with ferrous alloys .It resists oxidation up to 900°C
Specific welding/repair of furnaces, crucibles and other components for high temperatures.
