Inconel 625, UNS N06625

Alloy 625 combines heat resistance, corrosion resistance and strength. Alloy 625 fasteners are used in environments from cryogenic to 1800º F (1000º C). Resistance to oxidation is a primary characteristic. Like Alloy C276, Alloy 625 is a nickel-chrome-molybdenum alloy. The addition of niobium creates a stronger material. Common applications are in marine environments and pollution control equipment.
