Inconel 718 is a high-strength, corrosion-resistant nickel-chromium alloy known for its excellent mechanical properties at elevated temperatures. Inconel 718 bars are a popular form of this alloy and are widely used in various industries, including aerospace, oil and gas, and automotive, among others.
Composition: Inconel 718 bars are primarily composed of nickel, chromium, and iron, with additional elements such as niobium, molybdenum, titanium, and aluminum. The alloy's composition is carefully balanced to achieve a combination of high tensile strength, excellent corrosion resistance, and good weldability.
High-Temperature Performance: One of the standout features of Inconel 718 bars is their exceptional performance at high temperatures. These bars maintain their strength and structural integrity at temperatures ranging from cryogenic to over 1300°F (704°C). This makes them suitable for applications in jet engines, gas turbine operations, and other high-temperature environments.
