Super Alloy

        Superalloys are alloys that exhibit excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product. Chemical and petrochemical processing, Aero-engines, power plants, and oil and gas industries widely use these superalloys.

      Many of the industrial nickel-based superalloys contain alloying elements, including chromium (Cr), aluminum (Al), titanium (Ti), molybdenum (Mo), tungsten (W), niobium (Nb), tantalum (Ta) and cobalt (Co).
MIDHANI supplies most of the superalloys in the form of sheet, plate and bar forms.
