UTP HydroCav - UTP Schweissmaterial

Standards :
DIN 8555 : E 3-UM-55-ST
EN 14700 : E Fe3
UTP DUR 550 W
Basic coated stick electrode for heat resistant
surfacings on hot working tools with
high tempering resistance
Application field
UTP DUR 550 W is used for buildups on highly thermal stressed hot working tools, which are simultaneously
subject to abrasion, compression and impact. Main application fields are edges on forging dies, mandrils,
trimming tools, hot shear blades.
The elevated temperature hardness (up to 550° C) and the abrasion resistance are reached by addition of
tungsten, molybdenum, chromium, cobalt and vanadium. UTP DUR 550 W is suitable for the production
and repair of high quality hot working tools.
Welding properties
UTP DUR 550 W has excellent welding properties, a stable and regular flow, good bead appearance and
very easy slag removal.
Hardness of the pure weld metal (untreated)
55 - 57 HRC (at 20° C)
approx. 45 HRC (at 550° C)

Welding instruction
Clean welding area to metallic bright and preheat workpiece to 400° C. Preheating temperature should be
maintained during the whole welding operation. Slow cooling in oven or under cover, temper 1 - 2 x at 550°
C, if possible.
