Bohler NIBAS 625 PW-FD description: Rutile flux cored wire for high-quality joint welding of nickel-base alloys like Alloy 625 and Alloy 825 as well as of CrNiMo stainless steels with high Mo-content (e.g. "6Mo" steels). Additionally it is recommended for high-temperature or creep resisting, heat resisting and cryogenic materials, joining of dissimilar steels, and also for problem steels. Can be used for pressure vessel fabrication for service temperatures in the -196°C to +550°C range, otherwise up to scaling resistance limit of +1200°C (S-free atmosphere).
