Alloy 718 is a nickel based alloy material, also known as Inconel 718, which is a precipitation hardening nickel chromium alloy that can be used at temperatures up to 648 ° C. This alloy has extremely high strength, excellent creep stress fracture strength, and good corrosion resistance by adding a large amount of niobium and molybdenum, as well as aluminum and titanium.
Alloy 718 is mainly composed of elements such as nickel, chromium, and iron, as well as some other alloying elements such as molybdenum, aluminum, and titanium, which make it perform well in high temperatures and extreme environments. In addition, Alloy 718 is an important high-temperature nickel based alloy and stainless steel material, which has been widely used in various industries.
Its chemical composition mainly includes elements such as nickel, chromium, cobalt, and iron, among which nickel is its main component, accounting for about 50% of the total weight. The long-term use temperature range of this alloy is -253~650 ℃, and the short-term use temperature can reach 800 ℃. At temperatures below 650 ℃, it has high strength, good toughness, oxidation and corrosion resistance, as well as excellent processing and welding performance. Inconel718/alloy718 is suitable for manufacturing rings, blades, fasteners, and structural components in aviation, aerospace, and petrochemical industries.
