UTP 7008 anti-wear & anti-corrosion
Classifications rutile basic coated high efficiency electrode
DIN 8555 EN 14700
E 23-UM-250-CKTZ E Z Ni2
Characteristics and field of use
UTP 7008 is particularly suited for wear resisting cladding on hot working tools subject to
thermal load, such as forging saddles, forging jaws, forging dies, hot piercing plugs, hot
cutting knives, hot trimming tools and hot press rams.
UTP 7008 has excellent welding properties, a homogeneous, finely rippled bead appearance
due to the spray arc, very easy slag removal. The weld deposit is highly corrosion resistant,
scale resistant and workhardening. Machinable with cutting tools.
Hardness of the pure weld deposit : approx. 260 HB
workhardened approx. 500 HB

Welding instruction
Clean welding area. Preheat tools to 350 – 400 °C, temperature should be maintained during
the welding process. Slow cooling in oven. Hold stick electrode as vertically as possible
and with a short arc. Select lowest possible amperage, in order to reduce dilution with the
base metal. Re-dry stick electrodes that have got damp for 2 hours at 300 °C.
