Nc19FeNb Wrought nickel-base superalloy

Nc19FeNb Wrought nickel-base superalloy
Nc19FeNb Alloy is a nickel based superalloy , at -253 - 700 degree temperature range Nc19FeNb Alloy steel has good comprehensive properties. The yield strength of Nc19FeNb 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. Nc19FeNb Wrounght nickel-base superalloy equal material :UNS NO7718, Nc19FeNb,W.Nr.2.4668, NiCr19Fe19Nb5, NiCr19Nb5Mo3, Inconel 718
2. UNS NO7718 Wrounght nickel-base superalloy Chemical composition :
Nc19FeNb 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 .
Nc19FeNb alloy steel for nuclear energy applications, control of boron content (other elements unchanged), specific content determined by both sides. In order to Distinguish with Nc19FeNballoy in aerospace industry, When (B) ≤ 0.002% in Nc19FeNballoy steel, we call it as alloy Inconel 718A
