UTP 73 G 4 anti-wear
Classifications basic coated stick electrode
DIN 8555 EN 14700
E 3-UM-40-PT E Z Fe3
Characteristics and field of use
UTP 73 G 4 is, due to its toughness and heat resistance, ideally suited for surfacings on
parts and tools subject to abrasion, compression and impact at elevated temperatures.
Particularly for buildups on forging dies, die cast moulds, rollers, wobbler drives, hot-shear
blades. UTP 73 G 4 also offers an economic solution for the production of new tools, for
which a base material with an adequate tensile strength is recommended.
The stick electrode has excellent welding properties, a stable and regular flow, good bead
appearance and very easy slag removal. Heat resistant up to 550 °C.
Hardness of the pure weld bl: approx. 38 – 42 HRC

Welding instruction
Preheat the workpiece to 400 °C. Hold stick electrode as vertically as possible and with a
short arc. Take care of a slow cooling of the workpiece. Machining is possible with tungstene
carbide tools. Re-dry stick electrodes that have got damp for 2 hours at 300 °C.
