For welding steels used in the low temperature industries and in the nuclear industry.
Used in temperature conditions from -196°C to 600°C.
Weld deposit resistant to scaling at temperatures up to 1200°C (in a sulfur-free atmosphere).
Resistant to temperature shocks for austenitic steels, highly resistant to cracking and corrosion at high temperatures.
The most universal electrode for welding steel and cast iron elements of unknown origin, with unknown chemical composition and hardness, with unknown heat treatment, having previous hardfacing layers, that have suffered fatigue cracks (if repair is possible and there is no other option)
