UTP A 3545 NB description: 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. UTP A 3545 Nb 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.
