Inconel 718 Nickel Alloy Forged Round Bar

Inconel 718 (UNS N07718 / W.Nr. 2.4668) is a precipitation-hardenable nickel-chromium alloy that combines high strength with excellent corrosion resistance at temperatures up to 700°C. Our forged round bars are manufactured in strict compliance with ASTM B637 and AMS 5662/5663 standards, making them the ideal choice for demanding aerospace, oil & gas, and power generation applications.

Key Features

  • Exceptional High Temperature Strength: Maintains mechanical integrity at elevated temperatures up to 700°C with tensile strength ≥1275 MPa and yield strength ≥1035 MPa at room temperature.
  • Superior Corrosion Resistance: Excellent resistance to oxidation, pitting, and stress-corrosion cracking in aggressive environments including sour gas and seawater.
  • Precipitation Hardenable: Achieves optimal mechanical properties through solution annealing and aging heat treatment, eliminating the need for complex hardening processes.
  • Double Melting Process: Produced via VIM (Vacuum Induction Melting) followed by ESR (Electroslag Remelting) or VAR (Vacuum Arc Remelting) to ensure superior cleanliness and structural uniformity.
  • Wide Dimensional Range: Available in diameters from 10mm to 500mm and lengths from 1000mm to 6000mm, suitable for various machining and fabrication requirements.
