Inconel 718

Our materials are renowned for their exceptional strength, corrosion resistance, and thermal stability, making them suitable for critical applications across industries such as aerospace, oil & gas, petrochemicals, marine, power generation, and defense. We offer custom and standard sizes, ensuring optimal performance in both high-pressure and corrosive environments. With superior machinability, weldability, and dimensional accuracy, Namah Super Alloys delivers components that meet the most demanding international standards and client specifications.

Alloy 718 is a nickel-chromium alloy with additions of niobium & molybdenum which can be heat-treated to give high strength, good corrosion resistance, ease of formability and which can be welded with good resistance to strain age cracking. The alloy can be used at temperatures up to 700ºC.

Alloy 718 for the oil industry is heat treated such that the hardness does not exceed 40HRC which is the maximum allowed by NACE MR-01-75/ ISO 15156: 3 to prevent stress corrosion cracking. The major applications in this field are Valves and precision tubing.

Alloy 718 for aerospace and power generation is heat treated to give maximum strength and high creep resistance with typical hardness values exceeding 42HRC. The major applications are components for gas turbines, aircraft engines, fasteners and other high strength applications.
