Welding low alloy high strength steels

Low hydrogen electrode for welding quenched and tempered or micro alloyed steels.

The Charpy V impact strength is high, also at sub zero temperatures.

It has an excellent welder appeal thanks to the specific composition of the coating.

This coating is moisture resistant.
