Information needed about Inconel 718 alloy round bars
Inconel 718 round bars (UNS NO7718) are high-strength, corrosion-resistant nickel-chromium-based alloy bars essential for extreme high-temperature environments (up to 704°C/1300°F) in aerospace, rocket engines, and oil/gas industries. They exhibit excellent weldability, fatigue strength, and creep rupture strength. Commonly used standards include ASTM B637 and AMS 5662/5663.
What are the ASTM standards for Inconel 718 round bars?
Inconel 718 round bars can withstand temperatures up to 1300°F (700°C). They are used in power generation and in the manufacture of engine pistons and pump shafts. Typical specifications are AMS 5662 and ASTM B637. Please be sure to request the EN 10204/3.1B certification for this material from your supplier.
Our Inconel 718 round bars meet stringent specifications such as ASTM B637/ASME SB637, as well as equivalent standards such as AMS 5662 and AMS 5663. A complete range of specifications is available, with diameters ranging from 5 mm to 500 mm and lengths from 100 mm to 3000 mm and above. We also offer a variety of shapes including round, square, hexagonal, rectangular, wire, and billets, with surface finishes including bright, polished, and black. All products comply with NACE MR0175/ISO 15156 standards for enhanced performance.
