Features
- This nickel alloy can be used in various intense corrosive environments at high temperatures.
- This alloy shows excellent oxidation resistance up to 1180 ℃.
- In addition to excellent corrosion resistance and oxidation resistance, this alloy has both high strength and workability, and can be strengthened by cold working.
- This alloy shows excellent mechanical properties even at low temperatures.
- Anti-stress corrosion cracking due to chloride ion and corrosion resistance to pure water are good, so this alloy is used for parts for nuclear reactors.
- This alloy has excellent corrosion resistance against alkali at high temperature.
