Brief Introduction to the Properties of Inconel 718 Alloy Plate

Inconel 718 is a high-strength nickel-based superalloy plate known for its excellent properties over a wide temperature range, from cryogenic temperatures to approximately 704°C (1300°F). It exhibits high tensile strength, yield strength, and creep-rupture strength, along with good resistance to oxidation and corrosion due to its nickel and chromium content. This age-hardenable alloy is also nonmagnetic and nonsparking, making it suitable for high-performance applications in aerospace, power generation, and other demanding industries.

What are the standards for Inconel alloy 718?

INCONEL alloy 718 (UNS N07718/W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel-chromium alloy with a service temperature range of -200°C to 700°C. This age-hardenable alloy is easy to fabricate, even into complex parts.
