Nickel 718 Alloy Forged Bar
Nickel 718 Alloy Forged Bar Properties and Advantages
Nickel alloy 718 (Inconel 718) forged bar offers a unique combination of high strength, excellent creep-rupture strength, and exceptional corrosion and fatigue resistance, even at elevated temperatures up to approximately 700°C (1300°F). Key advantages include excellent mechanical properties over a wide temperature range, good weldability and fabrication processability, superior resistance to chloride stress corrosion cracking and sulfide stress cracking, and a high strength-to-weight ratio. These properties make it the material of choice for demanding applications in the aerospace, gas turbine, oil and gas, and chemical industries.
What are the properties of 718 nickel alloy?
718 alloy is a precipitation-hardenable nickel-based alloy with extremely high yield strength, tensile strength, and creep-rupture properties at temperatures up to 700°C. 718 alloy exhibits a slow age-hardening reaction, meaning it does not spontaneously harden during heating and cooling, making it suitable for annealing and welding.
