Air 9160 C E-Z6NCT25 - Introduction and Application

Super alloys or high performance iron-based. these alloys can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods.super alloys contain good oxidation and creep resistance and are available in varied shapes. These alloys can function under high mechanical stress and high temperatures and also in places that require high surface stability. Heat resistant steel with high strength, creep resistance, low magnetic permeability and high oxidation resistance. Endurance properties are obtained by emitting MC, M6C carbides by means of nickel, titanium and aluminum.It retains the appropriate mechanical properties to a temperature of about 650 - 700 ℃. In addition, it exhibits suitable strength properties at extremely low temperatures. Heat resistant to a temperature of about 800 - 900 ℃.Used as a steel for aviation and power engineering for heavy-duty rotors, gas turbine blades, steam turbines, pressure equipment parts and reactors, jet engines and rockets, exhaust systems. Also used in cryogenics and cryotechnics.Super alloy 1.4980, X6NiCrTiMoVB25-15-2, A-286, Grade 660 is used in gas turbine forgings, fasteners, superchargers, cryogenic equipment, missile components, corrosive deep well hardware and jet engines.
