Neil Metals, located in Kolkata, India, stands out as a top manufacturer and supplier of high-performance Inconel 718 Forgings. They’ve earned the trust of industries that require outstanding strength, heat resistance, and corrosion performance. With a reputation for precision engineering and a strict commitment to global standards, Neil Metals supplies Inconel 718 forgings for critical applications across aerospace, power generation, chemical processing, and marine sectors. Thanks to their advanced production capabilities and unwavering focus on quality, each forging they produce guarantees superior reliability, precise dimensions, and robust mechanical integrity. Their customized solutions are designed to meet the demanding requirements of high-temperature, high-pressure, and corrosive environments.
Inconel 718 Forgings are made from nickel-chromium-based superalloys, featuring significant amounts of iron (17–21%), chromium (17–21%), niobium (4.75–5.5%), molybdenum (2.8–3.3%), along with titanium and aluminum. This unique blend provides impressive tensile and yield strength, along with remarkable resistance to creep, corrosion, and oxidation. The alloy can achieve tensile strength up to 1380 MPa and yield strength around 1100 MPa after precipitation hardening. Inconel 718 remains stable and performs well at temperatures reaching 700°C, showcasing excellent fatigue and stress corrosion resistance, making it a perfect fit for the demanding conditions of aerospace and power generation.

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 face extreme thermal and mechanical stress. In aerospace, they’re crucial for jet engines, turbine discs, and structural components that need to withstand high fatigue. Power plants rely on them for gas turbines, fasteners, and heat-resistant parts. In the oil and gas sector, you’ll find Inconel 718 forgings in downhole tools, valves, and high-pressure seals. The chemical processing industry also benefits from them, using them in reactor vessels, piping systems, and pump components that come into contact with corrosive substances. Their excellent weldability, strength retention, and long service life make Inconel 718 forgings absolutely essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
