UTP 7015 Mo
Basic coated NiCrFe stick electrode
for high temperature applications
Application field
UTP 7015 Mo is predominantly used for joining identical heat resistant NiCrFe-allyos, heat resistant austenites,
cold tough Ni-steels, and for joining heat resistant austenitic-ferritic materials, such as 2.4816 (NiCr
15 Fe), 2.4951 (NiCr 20 Ti), 1.4876 (X10 NiCrTiAl 32 20), 1.4941(X8 CrNiTi 18 10). Specially also used for
joinings of high C content 25/35 CrNi cast steel to 1.4859 or 1.4876 for petrochemical installations with
working temperatures up to 900° C.
Properties of the weld metal
The welding deposit of UTP 7015 Mo is hot cracking resistant, does not tend to embrittlement and is scale
resistant and resistant to cavitation at high temperatures.

Welding instructions
Hold stick electrode as vertically as possible with a short arc, only a very little weaving. Fill end crater carefully.
Interpass temperature max. 150° C. Re-dry stick electrodes for 2 – 3 h / 250 – 300° C.
