Description:

An alloy of nickel chromium and molybdenum. Giving medium strength (from room temperature to 816°C), and 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, 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.

Alloy 625 can be hot worked in the temperature range 950-1180°C, although best microstructure is obtained when the final reduction is at the lower end of the forging range.

Alloy 625 is normally stocked in the annealed condition to provide good strength and hardness below 35HRC (to prevent stress corrosion resistance).
