Common Trade Names: Inconel 625, Chornin 625, Altemp 625, Nickelvac 625, Haynes 625 Nicrofer 6020
Inconel 625 is a nonmagnetic, corrosion and oxidation resistant, nickel-base alloy. It has high strength and toughness in the temperature range cryogenic to 2000°F (1093°C) which is derived largely from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix. Nickel alloy Inconel 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions.
