Bohler NIBAS 625-IG description: GTAW rod for high-quality joint welding of high-molybdenum nickel-base alloys (e.g. Inconel 625 and Incoloy 825) as well as of CrNiMo steels with high Mo-content (e.g. "6Mo" steels). Additionally this brand is recommended for
high-temperature or creep resisting, heat resisting and cryogenic materials, for low-alloy problem steels and joining dissimilar materials. Can be used for pressure vessel fabrication for service temperatures from -196C to +550C, otherwise up to scaling resistance limit of +1200C (S-free atmosphere). Due to the weld metal embrittlement between +600-850C, this temperature range should be avoided.
