Learn about Inconel 718 alloy fasteners
Inconel 718 is a precipitation-hardenable nickel-chromium alloy known for its excellent strength, corrosion resistance, and weldability, particularly at high temperatures. It's commonly used in aerospace, gas turbines, and other demanding applications requiring high strength and resistance to extreme environments.
What are the three main properties of Inconel 718?
Inconel 718 is a precipitation-hardening nickel-chromium alloy containing significant amounts of iron, niobium, and molybdenum, along with smaller amounts of aluminum and titanium. It combines corrosion resistance with high strength and excellent weldability, including resistance to post-weld cracking.
