Inconel 718 is a nickel chromium molybdenum alloy. It is used to resist all kinds of severe corrosion, such as pitting corrosion and crevice corrosion.The alloy can be used for a long time at a low temperature of 1200 ° F.One of its remarkable features is the addition of niobium, which allows age hardening, thus allowing annealing and welding, without spontaneous hardening during heating and cooling.
