德国UTP 068 HH镍基焊条UTP 068 HH nickel alloys
Classifications basic coated NiCrFe stick electrode
EN ISO 14172 AWS A5.11 Material-No.
E Ni 6082 (NiCr20Mn3Nb) E NiCrFe-3 (mod.) 2.4648
Characteristics and field of use
UTP 068 HH is predominantly used for joining identical or similar heat resistant Ni-base
alloys, heat resistant austenites, cold tough Ni-steel, and for joining heat resistant austenitic-
ferritic materials, such as 2.4817 (LC NiCr15Fe), 1.4876 (X10 NiCrTiAl 32 20), 1.4941
(X8 CrNTi 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.
The welding deposit is hot cracking resistant and does not tend to embrittlement.
The welding deposit of UTP 068 HH is hot cracking resistant, does not tend to embrittlement
and is scale resistant at high temperatures.
