Inconel nickel-chromium-iron heat-resistant and corrosion-resistant alloys.

Inconel is a registered trademark of the International Nickel Co.

Nickel-chromium alloy inconel is an austenitic superalloy with nickel as the main component. Due to the solid solution strengthening effect of molybdenum and niobium contained in nickel-chromium alloys, it has ultra-high strength and extraordinary fatigue resistance in the range from low temperature to 1093 °C. It is widely used in aviation industry and is suitable for production under 1100 °C. Low load oxidation resistant parts.

It has high tensile strength, fatigue strength, creep strength and rupture strength at 700℃, high oxidation resistance at 1000℃, stable chemical properties at low temperature, good weldability, and easy workability.

Although the alloy is designed for the strength to adapt to high temperature environments, the high content of chromium and molybdenum in the alloy has high resistance to corrosion spots and fission corrosion in many corrosive media, ranging from highly oxidizing environments to general corrosive environments. Excellent corrosion resistance properties. It also has a strong anti-corrosion effect on chloride-polluted media such as seawater, geothermal water, neutral salt and brine.

At the same time, the alloy has high formability and is easier to weld than many nickel-based alloys. In the welded condition, the alloy still has the ability to resist inter-gold corrosion. It has good tensile properties and fatigue properties from low temperature to 980℃, and is resistant to stress corrosion in salt spray atmosphere.

It can be used as aero engine parts, jet engine, aerospace structure layout, chemical equipment, bellows compensator expansion joints, modern garbage disposal equipment, occasions where it contacts seawater and bears high mechanical stress, marine structures, seawater environment, etc.
