They cater to industries that require exceptional strength and reliability. Known for their precision engineering and strict quality standards, this company produces forgings that comply with international specifications, ensuring they deliver superior durability and performance even in extreme conditions. With a wealth of expertise in metallurgy and a strong commitment to innovation, Phehlukwayo Metal offers tailored solutions to clients in the aerospace, energy, and marine sectors. Their Inconel 718 Forgings are celebrated for their remarkable resistance to corrosion, oxidation, and high-temperature deformation, making them a trusted choice around the globe.
Inconel 718 Forgings are nickel-chromium-based superalloys that gain their strength through precipitation hardening. Typically, they consist of 50–55% nickel, 17–21% chromium, 4.75–5.5% niobium, and 2.8–3.3% molybdenum, along with trace amounts of titanium and aluminum. These components provide excellent high-temperature strength, along with impressive resistance to corrosion and oxidation, as well as outstanding creep and fatigue performance. Inconel 718 retains its mechanical properties across a broad temperature range, reaching up to 700°C (1292°F). Its tensile strength falls between 1,240 to 1,380 MPa, with a yield strength of about 1,070 MPa, and it maintains good toughness and ductility even under extreme operating conditions, making it perfect for demanding industrial applications.

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 are extensively utilized in the aerospace industry for turbine engines, airframes, and exhaust systems, thanks to their ability to endure high temperatures and stress. They also play a crucial role in the energy sector, being essential for gas turbines, nuclear reactors, and chemical processing equipment, where exceptional corrosion and oxidation resistance is vital. Furthermore, these forgings are employed in marine and petrochemical industries, where durability in harsh environments is a must. Their strength, fatigue resistance, and stability under extreme thermal conditions make them an ideal choice for a variety of applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
