Inconel 625, N06625, 2.4856, Nickel Alloy Strip
Inconel 625 is a nickel-chromium-molybdenum alloy with niobium which is well suited for a wide range of severe corrosive environments. The alloy composition provides a product which performs well at elevated temperatures up to 1800°F. The strength can be increased by cold working.
The alloy is readily formed in the annealed temper, and can be joined by the standard welding and brazing processes.
Available Sizes:
Inconel 625 is available as strip product in thicknesses from 0.001” to 0.025” (0.0254 mm to 0.635 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM B443, AMS 5599 and UNS N06625.
We can also supply product to AMS 5879 (UNS N06626) for demanding fatigue applications, which incorporates double melting, and restrictive limits for Carbon and Nitrogen.
