Inconel 718 / NO7718 / 2.4669
Classification :
PRODUCT DETAILS
一、 N07718 nickel-based alloy has good comprehensive properties in the temperature range of -253~700℃. The yield strength below 650℃ ranks first among deformed high-temperature alloys. It also has good fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, as well as good processing performance, welding performance and long-term organizational stability.
二、 The chemical composition of the alloy is divided into 3 categories: standard composition, high-quality composition, and high-purity composition. The high-quality composition reduces carbon and increases niobium on the basis of the standard composition, thereby reducing the amount of niobium carbide, reducing fatigue sources and increasing the amount of strengthening phases, improving fatigue resistance and material strength. At the same time, it reduces the content of harmful impurities and gases. The high-purity composition reduces the content of sulfur and harmful impurities on the basis of the high-quality standard, and improves the purity and comprehensive performance of the material.
INCONEL 718 alloy for nuclear energy applications needs to control the boron content (other elements remain unchanged), and the specific content is determined by negotiation between the supply and demand parties. When w(B)≤0.002%, in order to distinguish it from INCONEL 718 alloy used in the aerospace industry, the alloy grade is INCONEL 718A.
三、N07718 high temperature alloy characteristics
1. High tensile strength, fatigue strength, creep strength and fracture strength at 700°C
2. High oxidation resistance at 1000°C
3. Stable chemical properties at low temperatures
4. Good welding performance
四、N07718 Application areas
a Aircraft engine parts
b Various elastic elements and grids in the nuclear energy industry
c Parts used in the petroleum industry
d Chemical industry
e Nuclear engineering
