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

Clean welding area, preheating temperature 450 – 600° C, very slow cooling. Hold stick electrode
vertically and with a short arc and lowest possible amperage. Redry stick electrodes that have
become damp for 2 h / 300°C.
Current type DC (+) / AC
