Description
INCONEL Alloy 625
INCONEL® alloy 625 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. Iconel® alloy 625 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.
Alloy 625 is generally supplied in the annealed condition, to provide utmost stability during fabrication and subsequent service. Inconel Alloy 625 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® alloy 625 and used in seawater heat exchangers in refineries, power plants, and offshore topside services that often need this material.
INCONEL® alloy 625 is also used extensively in the aerospace, automobile, chemical processing, oil extraction, oil refining, marine, waste treatment, pulp & paper and power industries. Recent developments have led to INCONEL® alloy 625 being used as weld overlaid or co-extruded product for superheater tubing and is playing a major role in the worldwide growth of Municipal Waste To Energy and bio fuel production.
