Inconel 625
Overview of Inconel 625
Inconel625 alloy is a solid-solution strengthened nickel-based deformable high-temperature alloy with molybdenum and niobium as the main strengthening elements.
It features excellent corrosion and oxidation resistance, maintains good tensile and fatigue properties from low temperatures to 980℃, and is resistant to stress corrosion in salt spray atmospheres.
Inconel 625 alloy is designated as UNS N06625. Common standards include ASTM B366, ASTM B446, ASTM B443, ASTM B444, AMS5666, AMS5599, AMS5581.
Inconel 625 is usually used in the following forms: Inconel 625 welding wire, Inconel 625 bar and Inconel 625 plate.
