UTP 85 FN cast iron
Classifications Graphite-basic coated FeNi stick electrode
EN ISO 1071 AWS A5.15
E C NiFe-1 3 E NiFe-Cl
Characteristics and field of use
UTP 85 FN is suitable for surfacing and joining of all grades of cast iron, particularly nodular
cast iron (GGG 38-60) and for joining these materials with steel and cast steel.
UTP 85 FN has excellent welding properties and a smooth, regular flow, a high deposition
rate and a finely rippled bead appearance. Very economic for construction and production
welding on nodular cast iron parts. High current carrying capacity thank to a bimetallic core
wire.

Welding instruction
Prior to welding, the casting skin has to be removed from the welding area. Hold the stick
electrode vertically and with a short arc. Apply string beads – if necessary, with very little
weaving. Peen the deposit after slag removal for the purpose of stress relief. Avoid high
heat concentration.
