UTP ANTINIT DUR 300
Basic coated CrNi stick electrode for wear resistant
surfacings in the armatures construction
Application field
UTP ANTINIT DUR 300 is suitable for wear and corrosion resistant surfacings on ferritic and austenitic
base materials in the armatures construction. The extremely low Co-content permits the use in the nuclear
area for claddings on valve seats.
Properties of the weld deposit
The weld deposit of UTP ANTINIT DUR 300 has a ferritic-austenitic structure in a ratio of approx.
45 : 55 %. This alloy distinguishes itself by a high resistance against corrosive medias. It has also a high resistance
against abrasion, cavitation and erosion. The ferritic-austenitic weld deposit is IK-resistant and has a
low friction coefficient.

Welding instruction
Oxides must be removed in the welding area. Stick electrodes are weldable as vertically as possible with a
short arc and in string bead technic. If one-layer-welding has to be made, pre-heating and interpass temperature
have to be adjusted to the base material. If several layers are applied, the workpiece should be preheated
to min 300 – 400° C. Pre-heating temperature should be maintained during the whole welding
operation. Pay attention to an uniform and homogeneous temperature. The entired wear and corrosion resistance
will be obtained on multi-pass applications. Re-dry stick electrodes 2 - 3 h at 250 - 300° C.
