Inconel 625 (UNS N06625, GH3625, 2.4856) is a solid-solution nickel-chromium-molybdenum bolting grade rated to 650°C and supplied to ASTM B446, ASTM B564 and AMS 5666 at 930 MPa tensile and 517 MPa yield in the annealed condition. A PREN above 50 sits behind the corrosion side, so inconel 625 bolts and inconel 625 fasteners deliver a combination of heat and corrosion resistance no stainless steel offers.

FAQ

Inconel 625 questions we get most

Inconel 625 fasteners are solid-solution: 930 MPa tensile, outstanding corrosion resistance, no aging required. Inconel 718 is precipitation hardened: 1275 MPa tensile but less corrosion margin and it must be aged. Choose inconel 625 bolts for corrosion, 718 for load.
