Oerlikon Nifil 59 description: NIFIL 59 is used for welding of Ni-alloys with high CrMo content, to match with Alloy 59 base material. Excellent resistance against pitting, chloride-induced stress corrosion cracking, and crevice corrosion in acid sulfur phosphorus and chlorine surroundings. The high level of Mo in Alloy 59 is similar to alloys C276 and C4 but performance in a wide range of more oxidising media is significantly enhanced by increasing Cr to 23%. Total alloying exceeds the level typically present in alloy C22; it is therefore considered suitable for welding this group of alloys.
