HAYNES X-750 alloy
HAYNES X-750 alloy is a nickel-based precipitation hardening superalloy with high strength up to temperatures of 870°C. This alloy is widely used in aircraft and other branches of industry in the form of forged and composite components.
The Haynes X750 alloy in brief:
- Nickel-chromium alloy
- Similar to alloy 600
- Additional aluminum and titanium for improved mechanical properties at temperatures up to 704°C
- Often used in gas turbines, nuclear reactors and aircraft
This alloy has been developed on the basis of alloy 600, with the addition of aluminum and titanium. This makes the alloy precipitation hardening.
Product description Haynes x-750 alloy
The strength is higher than that of Alloy 718 up to a temperature of 760°C. At higher temperatures, the strength of Alloy R-41 is higher than that of Alloy X-750. Alloy X-750 can be cold deformed in the solution annealed state but also hot above 1040°C. Weldability is reasonable, however, with heavy entrapment, cracking may occur as a result of strain age cracking.
