Utp 068 HH

UTP 068 HH is a nickel-chromium-iron stick electrode that is predominantly used for joining heat resistant nickel-base alloys, austenites, and ferritic-austenitic materials. The welding deposit is hot cracking resistant, does not tend to embrittlement, and can withstand high temperatures. It has typical compositions of 0.025% C, 0.4% Si, 5.0% Mn, 19.0% Cr, 1.5% Mo, 2.2% Nb, and the balance is nickel and 3.0% iron.

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.
