Inconel 718 Alloy: Properties, Forms, and Applications
Inconel 718 is a high-strength, corrosion-resistant nickel-chromium superalloy renowned for its exceptional performance in extreme environments. Valued for its stability at temperatures ranging from cryogenic up to 700°C (1300°F), alloy 718 has become an indispensable material for critical applications in aerospace, oil & gas, and high-performance industrial sectors. Its unique combination of properties makes it a premier choice for turbine components, downhole tools, and other high-stress components where reliability is non-negotiable.
As leading inconel 718 suppliers, we provide this superior material in various forms to meet your specific project requirements, including Inconel 718 sheet, Inconel 718 plate, and Inconel 718 round bar. Our inventory is sourced from globally accredited mills and is available for delivery across the UAE and worldwide, ensuring you receive certified, high-quality materials on time.
What Is Inconel 718?
Inconel 718 is a precipitation-hardenable nickel-based alloy, meaning it derives its exceptional strength from a specific heat treatment process that forms fine secondary phases within its metallic structure. This process significantly enhances its mechanical properties, allowing it to withstand immense physical and thermal stresses without deforming.
One of the defining characteristics of alloy 718 is its slow age-hardening response, which gives it excellent weldability without spontaneous hardening or cracking during heating and cooling. This makes fabrication and repair more manageable compared to other precipitation-strengthened superalloys. The Inconel 718 properties also include outstanding resistance to oxidation and various forms of corrosion, such as chloride-ion stress-corrosion cracking and sulfide stress cracking, which are common challenges in marine and sour gas environments.
When compared to other nickel alloys, Inconel 718 offers a superior combination of tensile, fatigue, creep, and rupture strength at elevated temperatures, making it the material of choice for the most demanding engineering challenges.
