德國UTP UP 6222 Mo焊絲UTP UP 6222 Mo UTP UP FX 6222 Mo SAW Wire Classifications high-alloyed EN ISO 18274: AWS A5.14: S Ni 6625 (NiCr22Mo9Nb) ERNiCrMo-3 Characteristics and field of use UTP UP 6222 Mo and the flux UTP UP FX 6222 Mo are applied for joint welding of base materials with the same or with a similar comb, e. g. Alloy 625 (UNS N06625) or NiCr22Mo9Nb, Material-No. 2.4856 or mixed combinations with stainless steels and carbon steels. Furthermore the wire-flux combination is used for cold-tough Ni-steels, e. g. X8Ni9 for LNG projects. UTP UP 6222 Mo / UTP UP FX 6222 Mo is also applied0n alloyed or unalloyed steels for cladding of corrosion resistant plants.
