ASTM B443 covers two materials: Nickel-chromium-molybdenum-niobium alloy (Inconel 625, UNS N06625) and Nickel-chromium-molybdenum-silicon alloy (UNS N06219). Among them, Inconel 625 is a more commonly used alloy. Nickel and chromium elements give these two alloys excellent oxidation resistance. Molybdenum ensures the material's resistance to reduction. Therefore, both alloys have good overall corrosion resistance. In Inconel 625, niobium plays an important role in solid solution strengthening, which gives the alloy higher strength.
