ALLOY718 is a precipitation-hardened nickel-chromium-iron alloy with significant amounts of niobium and molybdenum, and smaller amounts of aluminum and titanium. The alloy has good ductility in the annealed condition and high strength at temperatures up to 700°C (1300°F). It can be supplied in the solution-annealed and precipitation-hardened condition. 

• Good processing properties in the annealed condition 
• Good tensile, fatigue and creep rupture strength 
• High strength at elevated temperatures up to 700°C (1300°F) 
• Good oxidation resistance up to temperatures of 1000°C (1830°F) 
• Good mechanical properties in cryogenic environments 
• Good corrosion resistance at low and high temperatures, and resistance to stress corrosion cracking and pitting 
• Good weldability by arc and resistance welding processes (no post-weld cracking)
