Thermanit 625 TIG rod
Classifications high-alloyed
EN ISO 18274: AWS A5.14:
S Ni 6625 (NiCr22Mo9Nb) ERNiCrMo-3
Characteristics and field of use
Nickel based alloy high resistance to corrosive environment. Resistant to stress corrosion cracking.
Resistant to scaling up to 1100 °C (2012 °F). Temperature limit: 500°C (932°F) max. in sulphureous
atmospheres. High temperature resistant up to 1000 °C (1832 °F). Cold toughness at subzero temperatures
as low as –196 °C (–321 °F). For joining and surfacing work with matching/similar corrosion-
resistant materials as well as0n matching and similar heat resistant， high temperature resistant
steels and alloys. For joining and surfacing work0n cryogenic austenitic CrNi(N) steels/cast steel
grades and0n cryogenic Ni steels suitable for quenching and tempering.
