UTP 73 G 2 anti-wear
Classifications basic coated stick electrode
DIN 8555 EN 14700
E 3-UM-55-ST E Fe8
Characteristics and field of use
UTP 73 G 2 is, due to its high hardness, toughness and heat resistance ideally suited for
buildups on parts subject to severe friction, compression and moderate impact loads at
elevated temperatures, such as back centers, gripping pliers, gliding and guiding surfaces,
hot and cold punching tools, valves, slides, hot-shear blades, extrusion press pristons,
forging tools, stripping columns, trimming tools, roll mandrils, punching tools for sheet
metals. UTP 73 G 2 is used to good advantage for the production of new cold and hot working
tools. In such cases cladding is made on base material with an accordingly high tensile
strength.
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 metal: 55 – 58 HRC

Welding instruction
Preheat the workpiece to 400 °C. Hold stick electrode as vertically as possible and with
a short arc. Allow the workpiece to cool down slowly. Finishing by grinding. Re-dry stick
electrodes that have got damp for 2 hours at 300 °C.
