Inconel 718/UNS N07718 sheet/bar/pipe

‌Inconel series alloys ‌ belong to the austenitic nickel-chromium base superalloy series, widely used in a variety of extreme environments. Due to its excellent corrosion resistance, high temperature strength and mechanical properties, Inconel alloy has a wide range of applications in aerospace, petrochemical, power generation and other fields.
The main components of Inconel alloys include nickel, chromium, iron, and sometimes other elements such as aluminum, titanium, or molybdenum. These elements give Inconel alloys excellent strength and oxidation resistance at high temperatures. For example, Inconel 600 alloy has good thermal strength and high plasticity below 700 ° C, while having good high-temperature corrosion resistance and oxidation resistance ‌.

Product Details

Inconel 718 has excellent corrosion resistance at high and low temperatures and good resistance to stress-corrosion cracking and pitting corrosion. Alloy 718 has good performance in hostile environments containing H2S, CO2, chlorides, sulfides and free sulfur at selected temperatures. Alloy 718 is commonly used for cryogenic storage tanks, downhole shafts and wellhead parts.
