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.
These forgings are widely utilized in industries where exceptional heat and corrosion resistance are crucial. In aerospace, they are found in turbine discs, engine components, and fasteners, thanks to their high-temperature strength and fatigue resistance. Power generation facilities use them in gas turbines, combustor parts, and high-pressure systems that face extreme thermal conditions. In the oil and gas industry, these forgings are prized for their durability in corrosive and high-pressure drilling environments. Moreover, they are also used in marine engineering, chemical processing equipment, and high-performance automotive systems that demand stable, long-lasting performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
