Application:

Hardfacing and repairing

Metallurgy (Steelworks)

Mining

Specially designed, universal high-alloy austenitic-ferrite CrNi electrode with embended microelements Mo, V, Co and N, for welding and regeneration of elements made of all types of steel and cast steel (hard-to-weld steels, easy-to-weld steels, high-hardness steels, spring steels, etc.).
Especially recommended for welding steels of various and unknown composition, such as: unalloyed or alloy structural steels with high-alloy chromium or chromium-nickel steels, for joining or overlaying manganese steels and welding them with other steels.
Provides very good corrosion and oxidation resistance up to 1000°C.
Welds steels of unknown composition successfully.
Thanks to its versatility, it does not require any special skills or technology: works on all AC or DC arc welding machines, does not require surface cleaning, works on grease, rust, moisture, paint, etc.
The slag rises by itself.
Works in all positions
Even inexperienced welders will be able to make a correct weld
It is necessary to preheat the component to 200ºC or higher when welding special steels such as high alloy tool steels.
