Bohler FOX NIBAS 625 description: Basic electrode, core wire alloyed for welding the nickel-base alloy Inconel 625 and Inconel 825 as well as CrNiMo-steels with high molybdenum content (e.g. "6 Mo" steels). It is also recommended for high temperature and creep resisting steels, heat resisting and cryogenic materials, dissimilar joints, and lowalloyed problem steels. Suitable in pressure vessel fabrication for -196C to +550C, otherwise up to the scaling resistance temperature of +1200C (S-free atmosphere). Due to the weld metal embrittlement between 600-850°C, this temperature range should be avoided. Highly resistant to hot cracking. Furthermore C-diffusion at high temperature or during heat treatment of dissimilar joints is largely reduced. Extremely resistant to stress corrosion cracking and pitting (PREN 52). Thermal shock resistant, fully austenitic, low coefficient of thermal expansion between C-steel and austenitic CrNi (Mo)-slag removal, high resistance ighest quality requirements.
