Material Notes:
Nickel content to balance. High temperature stability even after aging in the 650-1040°C (1200-1900°F) range as evidenced by good ductility and corrosion resistance. Resists the formation of grain-boundary precipitates and is therefore suitable for use in most chemical process applications in the as-welded condition. C-4 resists stress-corrosion cracking and oxidizing atmospheres up to 1040°C (1900°F). It has exceptional resistance to hot contaminated mineral acids, solvents, chlorine and chlorine-contaminated media (organic and inorganic), dry chlorine, formic and acetic acids, acetic anhydride, seawater and brine solutions.
