Description

Alloy 625, a Nickel Alloy grade, combines nickel, chromium and molybdenum, giving high strength (from room temperature to 816°C), ease of fabrication, and excellent corrosion resistance. Alloy 625 is particularly useful in situations where oxidation resistance and avoidance of pitting is required. In the annealed condition, Alloy 625 is fully austenitic and is suitable for machining. Alloy 625 can be hot or cold worked (although as it does work harden, intermediate heat treatments are advisable), formed and welded. Broder Metals Group stock Alloy 625 in the annealed condition to provide good strength and hardness, and typical applications are where contact with sea water and other harsh chemical environments and high mechanical stresses apply. Different heat treatments are available: Annealed and Age hardened.
