Nickel-based Alloy
Precipitation-hardened nickelo alloys also contain a certain amount of iron, niobium and molybdenum, accompanied by small amounts of aluminum and titanium.
Nickel-chromium-molybdenum alloy, the addition of niobium elements, together with molybdenum to make the alloy basically hard, thus showing high strength properties without heat treatment strengthening.
Nickel-iron-chromium alloy, with addition of molybdenum and copper, has both oxidation resistance and reducing acid properties, resistance to stress corrosion cracking and local corrosion, such as pitting and crevice corrosion.
