INCONEL® 625 alloy is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance. It has become a standard material of construction in a wide variety of industrial applications, which is unusual for an alloy. Alloy 625 is valuable in that it is versatile and able to solve a wide variety of design and application problems.
INCONEL® 625 alloy consists of a solid solution alloy of nickel, chromium and molybdenum alloy with niobium added. When this combines with molybdenum it distorts the alloy’s atomic matrix, thus providing particularly high strength in the annealed condition without a deliberate strengthening heat treatment.This combination of elements creates superior resistance to a wide range of corrosive environments of unusual severity.
Alloy 625 is generally supplied in the annealed condition, to provide utmost stability during fabrication and subsequent service. INCONEL® 625 alloy has found to have a resistance to potable and salt or brackish water, where Chloride ions cause pitting and crevice corrosion to become established. As a result, pipelines for gathering sour gas have been built with solid (or clad) INCONEL® 625 alloy and used in
