Inconel 718 (N07718) nickel-based alloy is a precipitation-hardened nickel-chromium-iron alloy containing niobium and molybdenum.
In terms of chemical composition, Inconel 718 alloy is mainly composed of nickel, chromium, iron and other elements, and a small amount of carbon, manganese, silicon, molybdenum, copper, cobalt, aluminum, titanium, niobium, boron and other elements are added.
In terms of physical properties, the density of Inconel 718 alloy is 8.24g/cm³, and the melting temperature range is 1260～1320℃. These characteristics enable it to maintain stable performance even in high temperature and high pressure working environments.
In terms of processing and heat treatment, Inconel 718 alloy needs to be processed and heat treated at specific temperatures and environments to obtain the best performance.
Preheating, hot working, cold working, heat treatment and other processes need to be strictly controlled to ensure the quality and performance of the final product.
In addition, grinding and machining of Inconel 718 alloy also require specific technology and equipment. Due to its high work hardening rate, the processing equipment needs to be adjusted accordingly. At the same time, in order to ensure processing quality and efficiency, intermediate annealing is required during the processing.
In terms of welding, the precipitation hardening characteristics of Inconel 718 alloy make it very suitable for welding. No tendency to crack after welding and good welding performance make it easy to connect and assemble during the manufacturing process.
