To determine if Inconel 718 forgings meet your specific needs, assess their strength, corrosion resistance, and high-temperature performance against your application requirements. Consult with a supplier to ensure they meet the necessary specifications and certifications for your intended use.
Inconel 718 forgings are typically processed through hot working, which involves heating the material to a high temperature, followed by forging and shaping. The process is followed by heat treatment to enhance mechanical properties, including solution annealing and aging.
The ideal temperature range for forging Inconel 718 is between 1,800°F (982°C) and 2,100°F (1,149°C). This range ensures optimal workability and prevents material degradation during the forging process.
Inconel 718 Forgings find extensive use in industries that require exceptional strength and the ability to withstand extreme conditions. They’re commonly utilized in aerospace for turbine discs, jet engine components, and rocket motors, thanks to their capacity to endure high heat and stress. In the power generation field, you’ll find them in gas turbines, steam turbines, and nuclear reactors. The oil, gas, and chemical sectors rely on them for valves, pumps, and high-pressure equipment that face corrosive environments. Their blend of toughness, fatigue resistance, and long service life makes them an essential choice for these demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
