  • TIG rod for welding nickel-based alloys with a high molybdenum content (Alloy 625 or 825) and 6Mo steels.
  • Resistant to thermal shocks, stainless, fully austenitic.
  • Recommended for materials resistant to high temperatures, creep, for heat-resistant steels, cryogenic steels, for steels with limited weldability and for dissimilar joints.
  • It can be used for manufacturing pressure vessels.
  • High impact strength at very low temperatures - recommended for 9% Ni steel.
  • High resistance to hot cracking.
  • Carbon diffusion at high temperatures or during heat treatment is largely inhibited.
  • Extremely resistant to corrosion, stress and pitting cracking.
  • Low coefficient of thermal expansion.
  • In the temperature range of 600-850°C, the weld metal becomes brittle - this range should be avoided.
