ALLOY 625 | UNS N06625
Description
Alloy 625 is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance. Its outstanding strength and toughness is due to the addition of niobium which acts with the molybdenum to stiffen the alloy’s matrix. Alloy 625 has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. This alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.
