UNS NO7718 Wrought nickel-base superalloy

UNS NO7718 Wrounght nickel-base superalloy equal material :
Inconel 718, Nc19FeNb, , W.Nr.2.4668, NiCr19Fe19Nb5, NiCr19Nb5Mo3

UNS NO7718 Alloy is a nickel based superalloy , at -253 - 700 degree temperature range UNS NO7718 Alloy steel has good comprehensive properties. The yield strength of UNS NO7718 Alloy steel under 650 degree temperature is the best among all the Wrounght nickel-base superalloy With a good anti fatigue, anti radiation, anti-oxidation, corrosion resistance, and processability, good welding performance and long-term stability, to complex manufacturing various shapes of parts, in the aerospace, nuclear, petroleum industry, in the temperature range is widely used.


1.UNS NO7718 Wrounght nickel-base superalloy Chemical composition :
UNS NO7718 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 .
UNS NO7718 alloy steel for nuclear energy applications, control of boron content (other elements unchanged), specific content determined by both sides. In order to Distinguish with UNS NO7718 alloy in aerospace industry, When (B) ≤ 0.002% in UNS NO7718 alloy steel, we call it as alloy UNS NO7718A
UNS NO7718 Alloy steel property :
 UNS NO7718 Alloy melting temperature range : 260-1320 degree
 Inconel718 Alloy Density: 8.24g/cm3。
 UNS NO7718 Specifications and supply status :
We can supply forging parts (disc, the integral), cake, ring, bar (forging rod, bar, cold rolling, plate, wire rod), belt, tube, different shapes and sizes of fasteners, elastic components, delivery conditions agreed upon by both sides of supply and demand. Wire to the agreed delivery state into a disc delivery.
UNS NO7718 alloy Application and specific requirements:
Various pieces of a manufacturing and aerospace engines and rotating parts, such as disk, ring, casing, shaft, blades, fasteners, elastic element, gas conduit, sealing element and welding pieces of the structure; nuclear industrial applications of various elastic components and framework; application of manufacturing oil and chemical industry parts and other parts.
Key words: UNS NO7718 stock, UNS NO7718 competitive price, UNS NO7718 high quality, UNS NO7718 supplier, UNS NO7718 manufacturer.
