W/GZ 35 45 Nb |
Application field
Cr35Ni45Nb is suitable for joining and surfacing on identical and similar high heat resistant cast alloys (centrifugal- and mould cast parts), such as G X-45NiCrNbSiTi 45 35.
The main application field is for tubes and cast parts of reformer and pyrolysis ovens at temperatures up to 1175° C / air.
Properties of the weld metal
The weld deposit is applicable in a low sulphur, carbon enriching atmosphere up to 1175° C and has an excellent creep strength and a good resistance against carburization and oxidation.
