Inconel 718 Wrought nickel-base superalloy
Inconel 718 Alloy is a nickel based superalloy , at -253 - 700 degree temperature range Inconel 718 Alloy steel has good comprehensive properties. The yield strength of Inconel 718 Alloy steel under 650 degree temperature is the best among all the Wrounght nickel-base superalloy With a good anti fatigue, anti radiation, antioxidation, corrosion resistance, and processability, good welding performance and long-term stability, to complexmanufacturing various shapes of parts, in the aerospace, nuclear,petroleum industry, in the temperature range is widely used.
1.Inconel 718 Wrounght nickel-base superalloy equal material : UNS NO7718, Nc19FeNb, , W.Nr.2.4668, NiCr19Fe19Nb5, NiCr19Nb5Mo3
2. Inconel 718 Wrounght nickel-base superalloy Chemical composition :
Inconel 718 Alloy steel chemical composition is divided into 3 categories: standard components, high quality components, high pure component,High quality components based on standard components of the carbon reduction and increase of niobium, thereby reducing the number of niobium carbide,reduce fatigue and increase the amount of strengthening phase, improve the anti fatigue performance and strength of materials. At the same time, reduce the harmful impurities and gas content. High pure components is to reduce the content of sulfur and harmful impurity in high quality standard basis, improve the comprehensive performance of the material purity .Inconel 718 alloy steel for nuclear energy applications, control of boron content (other elements unchanged), specific content determined by both sides. In order to Distinguish with Inconel 718 alloy in aerospace industry, When (B) ≤ 0.002% in Inconel 718 alloy steel,we call it as alloy Inconel 718A
