فیلر UTP A 3545 Nb

فیلر تخصصی UTP 3545 Nb ، یا WZ 35 45 Zr مناسب برای جوشکاری فولادهای ریخته گری با دمای بالا مانند لوله های واحد های ریفرمر ( REFORMER ) پتروشیمی ها ، سانتریفیوژها و ...

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.
Welding characteristics and special 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.
Welding instruction
Clean welding area carefully. No pre-heating or post weld heat treatment. Keep heat input as low as
possible and interpass temperature at max. 150° C.
