UTP CELSIT 706 anti-wear & anti-corrosion
Classifications rutile coated stick electrode on Cobalt base, core wire alloyed
DIN 8555 EN 14700 AWS A5.13
E 20-UM-40-CSTZ E Z Co2 E CoCr-A
Characteristics and field of use
UTP CELSIT 706 is used for hardfacing on parts subject to a combination of erosion, corrosion,
cavitation, impact, pressure, abrasion and high temperatures up to 900 °C, such as
tight surfaces on fittings, valve seats and cones for combustion engines, gliding surfaces
metal-metal, highly stressed hot working tools without thermal shock, milling mixers and
drilling tools.
Excellent gliding characteristics, easy polishability, good toughness, nonmagnetic. Machining
by grinding or with tungsten carbide cutting tools.
UTP CELSIT 706 has excellent welding properties and a homogenenous, finely rippled seam
due to spray arc. Very easy slag removal.
Hardness of the pure weld deposit 40 – 42 HRC
Hardness at 500°C approx. 30 HRC
Hardness at 700°C approx. 160 HB

Welding instruction
Clean welding area, preheating temperature 450 – 600 °C, very slow cooling. Hold stick
electrode vertically and with a short arc and lowest possible amperage. Re-dry stick electrodes
that have become damp for 2 hours at 300 °C.
