X-750 Eqaulized - Super Alloy- Fry Steel

Super Alloy / X-750 EQUALIZED

X-750 is an equalized precipitation-hardenable nickel-chromium alloy used for its corrosion / oxidation resistance and high strength at high temperatures. X-750 is similar to Nickel 600, but has additional aluminum and titanium to increase the mechanical properties up to 1300F. This product offers excellent performance in highly stressed environments and is often used in gas turbines, nuclear reactors and aircraft structures. (UNS N07750)
