General properties
Alloy 625 / Inconel 625 ® (W-Nr. 2.4856; UNS N06625; DIN 17744, 17750-17752)
A nickel-chromium-molybdenum alloy with an addition of niobium that acts with the molybdenum to stiffen the alloy’s matrix and thereby provide high strength without a strengthening heat treatment. The alloy resist a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.
Used in chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.
