Alloy PE11 (UNS N09901) main elements are nickel, iron and chromium, but the additions of Aluminium, Titanium and Molybdenum makes the PE11 both precipitation hardened and solid-solution strengthened. PE11 is commonly used in gas turbines because of its high tensile ductility strength and as it was developed for use at 550°C (1020°F).
