Inconel X-750 Metal Tubes Customized Diameter Super Alloy Pipe
Inconel X-750 is a nickel-chromium alloy with excellent high-temperature properties and precipitation-hardening properties. It is also known as UNS N07750. The alloy has excellent corrosion resistance and oxidation resistance at high temperatures (up to 1300°F / 704°C). It is commonly used in high-temperature applications such as gas turbines, rocket engines and nuclear reactors, where strength and durability are critical.
Inconel X-750 alloy strength is somewhat less than that for Inconel 718 alloy up to about 1400°F (760°C),The alloy was developed from Alloy 600 by adding aluminium and titanium to make the alloy precipitation hardenable. Alloy X-750 also demonstrates good formability and excellent hightemperature oxidation resistance. Alloy X-750 offers outstanding performance in highly stressed environments, which is why it’s often used in gas turbines, nuclear reactors and aircraft structures.Alloy X-750 can be cold-formed in the annealed condition, and may also be hot-formed at temperatures of about 1900°F (1040°C) or above. Weldability is somewhat limited by susceptibility to strain age-cracking under conditions of heavy restraint. The alloy exhibits good resistance to oxidizing combustion gas environments at temperatures up to about 1600°F (870°C).
