Characteristics and field of use
The rutile coated stick electrode UTP 68 Mo is used for joining and surfacing of stabilized
and non stabilized CrNiMo steels and CrNiMo cast steels. The deposit is IC resistant with
stabilized base material up to + 400 °C working temperature.
The stick electrode is weldable in all positions except vertical down. Even flow, very easy
slag removal. Smooth, notch-free seam surface.
