Characteristics and field of use
The rutile coated stick electrode UTP 68 MoLC, with a low C content, is used for joining and
surfacing of identical, low carbon, austenitic CrNiMo steels and CrNiMo cast steels. The
weld deposit has, due to the low C content, a high resistance to intercristalline corrosion
and can be used for working temperatures up to + 400 °C.
The stick electrode is weldable in all positions except vertical down. The weld deposit is
smooth and fine rippled. Slag removal is very easy and without residues.
