Characteristics and field of use
UTP A 6170 Co is particularly used for joining heat resistant and creep resistant nickel base
alloys of identical and similar nature, high temperature austenitic and cast alloys, such as
1.4958 X5NiCrAlTi 31 20 UNS N08810
1.4959 X8NiCrAlTi 32 21 UNS N08811
2.4663 NiCr23Co12Mo UNS N06617
The weld metal is resitant to hot-cracking. It is used for operating temperatures up to
1100 °C. Scale-resistant at temperatures up to 1100 °C in oxidizing resp. carburizing
atmospheres, e. g. gas turbines, ethylene production plants.
