Inconel alloy 718 is a nickel-chromium-molybdenum alloy which has quite good combination property during -253~700℃.It is the most widely used superalloy due to its mechanical strength and creep up to 650℃. Alloy 718 has good corrosion resistance and ductility in a wide range of severely corrosive environments, pitting and crevice corrosion.
Melting range: 1260℃~1320℃
