Frequently Asked Questions
Common questions about Inconel 718 manufacturing and properties
What is Inconel 718?
Inconel 718 is a precipitation-hardening nickel-chromium alloy that contains significant amounts of iron, niobium, and molybdenum. It is one of the most widely used superalloys due to its exceptional combination of high-temperature strength, corrosion resistance, and fabricability. The alloy maintains excellent mechanical properties at temperatures up to 700°C (1300°F) and is particularly valued for its outstanding resistance to oxidation and corrosion in harsh environments.
How to machine Inconel 718?
Machining Inconel 718 requires specialized techniques due to its high strength and work-hardening characteristics. Key considerations include using carbide or ceramic cutting tools, maintaining proper cutting speeds (typically 30-60 SFM for turning), using high-pressure coolant, and employing climb milling strategies. The material tends to work-harden, so it's essential to maintain consistent cutting parameters and avoid dwell times. Proper tool selection, coolant application, and cutting strategies are crucial for achieving good surface finish and tool life.
What is Inconel 718 used for?
Inconel 718 is extensively used in aerospace applications, particularly in gas turbine engines, rocket engines, and aircraft structural components. It's also widely employed in oil and gas industries for downhole tools, valves, and wellhead equipment. Other applications include power generation (steam turbines, nuclear reactors), chemical processing equipment, and high-temperature industrial components. The alloy's combination of strength, corrosion resistance, and high-temperature performance makes it ideal for critical applications where reliability and longevity are paramount.
What is the composition of Inconel 718?
Inconel 718 has the following typical composition: Nickel (Ni) 50-55%, Chromium (Cr) 17-21%, Iron (Fe) balance, Niobium (Nb) 4.75-5.50%, Molybdenum (Mo) 2.8-3.3%, Titanium (Ti) 0.65-1.15%, Aluminum (Al) 0.20-0.80%, Cobalt (Co) ≤1.0%, Carbon (C) ≤0.08%, Manganese (Mn) ≤0.35%, Silicon (Si) ≤0.35%, Phosphorus (P) ≤0.015%, Sulfur (S) ≤0.015%, Boron (B) ≤0.006%. The precise balance of these elements gives Inconel 718 its unique combination of strength, corrosion resistance, and high-temperature performance.
What is the difference between Inconel 625 and 718?
Inconel 625 and 718 are both nickel-based superalloys but have different compositions and properties. Inconel 625 contains higher chromium (20-23%) and molybdenum (8-10%) but no niobium, while Inconel 718 contains niobium (4.75-5.50%) and lower molybdenum (2.8-3.3%). Inconel 718 is precipitation-hardenable and offers higher strength at elevated temperatures, making it better suited for structural applications. Inconel 625 is solution-strengthened and provides superior corrosion resistance, particularly in marine and chemical environments. Inconel 718 is more commonly used in aerospace and high-temperature applications, while Inconel 625 is preferred for corrosion-resistant applications.
