ALLOY 625

Nickel alloy

UNS N06625

Alloy 625 is a solid-solution-strengthened nickel-chromium-molybdenum superalloy known for its excellent corrosion resistance and very good mechanical properties over a wide temperature range. Its high molybdenum and niobium content gives it remarkable resistance to aggressive environments, particularly marine, chemical, and highly oxidizing environments.
