UTP LEDURIT 61 anti-wear
Classifications rutile-basic coated hardfacing stick electrode
DIN 8555 EN 14700 AWS A5.13
E 10-UM-60-GRZ EZ Fe14 ~ E FeCr-A 1
Characteristics and field of use
UTP LEDURIT 61 is suited for highly wear resistant claddings on parts subject to strong
grinding abrasion combined with medium impact, such as conveyor screws, scraper
blades, digging teeth, mixer wings, sand pumps. Also as a final layer on crusher jaws.
Welding properties
UTP LEDURIT 61 has excellent welding characteristics and a very easy slag removal. The
homogeneous and finely rippled seam surface does, for most applications, not require any
finish-ing by grinding.
Hardness of the pure weld deposit approx. 60 HRC
1 layer on steel with C = 0,15 % approx. 55 HRC
1 layer on high Mn-steel approx. 52 HRC

Welding instruction
Hold stick electrode as vertically as possible, keep a short arc. Preheating is in general not
necessary. On multipass-applications a cushion layer with UTP 630 is recommended in
order to prevent hardening cracks in the weld deposit. Re-dry stick electrodes that have got
damp for 2 hours at 300 °C.

Current type DC (+) / AC
