Inconel 718 is a high-strength alloy primarily composed of nickel and chromium, fortified with significant amounts of niobium and molybdenum. This sophisticated mix gives the forgings outstanding mechanical properties, including remarkable yield strength and excellent resistance to creep. They retain this toughness even when exposed to extreme temperatures, making them incredibly reliable under severe stress.

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.
The unique capabilities of our Inconel 718 forgings make them indispensable across several critical sectors. They are essential in the oil and gas industry for downhole tools and wellhead components, and in aerospace for jet engine parts and turbine disks. You’ll also find them in power generation turbines and within the automotive industry, wherever components must perform flawlessly under intense heat and pressure.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
