As an alloy, Inconel 625 consists primarily of nickel, chromium and molybdenum. In addition to these three main metals, trace amounts of niobium are added to the alloy. Alloying any metal will not only enhance its physical properties, but also its mechanical properties. At this point, the addition of molybdenum and niobium to ASTM B446 Inconel 625 forged bar helps strengthen the alloy matrix. The rigid matrix of Alloy 625 bar provides high tensile strength without the use of strengthening heat treatments.
