Alloy 625 Description
Alloy 625 is a non-magnetic , corrosion and oxidation resistant, nickel-chromium alloy. Its outstanding strength and toughness in the temperature range from cryogenic to 2000°F (1093°C) are derived primarily from the solid solution effects of the refractory metals Colombium and molybdenum in a nickel-chromium matrix. The alloy has excellent fatigue strength and stress corrosion cracking to chloride ions.
