    APPLICATION

    The economics of alloy X-750 coupled with its availability in all standard mill forms has resulted in applications in a wide variety of industrial fields. In gas turbines, it is used for rotor blades and wheels, bolts, and other structural members. Alloy X-750 is used extensively in rocket-engine thrust chambers. Airframe applications include thrust reversers and hot-air ducting systems. Large pressure vessels are formed from alloy X-750.

    Other applications are heat-treating fixtures, forming tools, extrusion dies, and test machine grips. For springs and fasteners, alloy X-750 is used from sub-zero to 1200°F.

    OVERVIEW

    Alloy X-750 is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F. Alloy X-750 also has excellent properties down to cryogenic temperatures.

    Alloy X-750 Characterized by:

    ● high tensile strength up to 705°C (1300°F)

    ● high creep and rupture strength up to 820 °C (1500 °F)

    ● high oxidation resistance up to 980 °C (1800 °F)

    ● excellent mechanical properties in cryogenic environments

    ● good corrosion resistance at high and low temperatures and high resistance to stress corrosion cracking

    ● good weldability by resistance and fusion processes

    For applications requiring high strength and ductility at service temperatures up to 1100°F, INCONEL alloy X-750 rod, bar, and forgings are given the following heat treatment:

    1625°F/24 hr, A.C. – Equalizing

    1300°F/20 hr, A.C. – Precipitation Heat Treatment

    This heat treatment is described by AMS 5667, which requires that material so heat-treated have the following minimum room-temperature properties. Hardness will lie in the range of 302-363 BHN.

    CORROSION RESISTANCE

    Alloy X-750 is resistant to a wide variety of industrial corrosives under both oxidizing and reducing conditions. It resists oxidation and attack by other high-temperature corrosion mechanisms.

    In hot corrosion tests for automotive applications, weight loss after exposure for 100 hours in 90% Na2SO4 +10% NaCl mixture in air was about 5%. Samples precoated with sodium chloride (by dipping in a hot saturated salt solution), suspended in a furnace at 1700°F and exposed for 100 hr to a moving gas stream of air containing 1% SO2 exhibited a corrosion penetration of approximately 0.007 in. An interesting feature of this alloy is its high resistance to chloride-ion stress-corrosion cracking even in the fully precipitation-hardened condition. Standard U-bend specimens of precipitation-hardened material (hardness, 33 Rc) showed no signs of cracking when exposed to boiling 42% magnesium chloride for 30 days.


    HOT FORMING

    Sufficiently powerful equipment is important when hot-forming alloy X-750 because of its resistance to deformation.

    The recommended temperature range for hot working alloy X-750 is 980 to 1200 °C (1800-2200°F) range. Cooling should be by water quenching or as fast as possible. Localized reheating is not recommended. Annealing after hot working is recommended to ensure maximum corrosion resistance. For hot working, the material may be charged into the furnace at maximum working temperature.


    COLD FORMING

    Cold working should be carried out on solution-annealed material. Alloy X-750 has a much higher work-hardening rate than austenitic stainless steel and the forming equipment must be designed accordingly.

    When cold working is performed, interstage annealing may become necessary.


    MACHINING

    Alloy X-750 is machined at practical and economical rates. Proper procedures, tooling, and conditions shall be taken. Because of precipitation-hardened alloy X-750’s high strength and hardness, rough machining is usually done before precipitation hardening. Finish machining then follows precipitation treating. Precipitation hardening relieves machining stresses; therefore, allowance must be made for possible warpage. A slight permanent contraction takes place during precipitation treating, but precipitation-treated material has good dimensional stability. Accurate dimensions and a good finish will result from following these practices.
