General description
Fully basic Ni-base high CrMoNb alloyed austenitic all position electrode
Extreme high resistance to:
- general and intergranular corrosion
- pitting and crevice corrosion
- stress corrosion cracking
Suitable for welding dissimilar joints; high resistance to hot cracking
High resistance to high temperature oxidation (max. 1200°C) and carburization
Good impact toughness at low temperatures (down to -196°C), suitable for 9% Ni steel
Current type
DC electr. +
Application advice
Welding with heat input max.1.5 kJ/mm
Interpass temperature max.150°C
