Product Description

Product Description

Inconel is a high-performance superalloy primarily based on nickel, designed for applications in extreme environments. It is renowned for its excellent oxidation resistance, corrosion resistance, and high-temperature strength, maintaining mechanical stability and strength at temperatures up to 1000°C (or even higher).

The composition of this alloy typically includes nickel (Ni), chromium (Cr), and iron (Fe), with additional elements like molybdenum (Mo), aluminum (Al), titanium (Ti), and cobalt (Co) added to enhance specific properties. Inconel alloys are widely used in aerospace, energy, petrochemical, marine engineering, and nuclear industries. Common grades such as Inconel 600, 601, 625, 718, and X-750 are tailored for different working conditions and requirements.

Its resistance to high-temperature oxidation and corrosion makes it the material of choice for turbine engines, heat exchangers, chemical processing equipment, and nuclear reactor components in demanding environments.

• Inconel 600: Mainly used in environments that require high temperature and oxidation resistance, such as chemical processing equipment and turbine engines.
• Inconel 625: Known for excellent corrosion resistance, widely used in marine, oil, and gas industries.
• Inconel 718: Commonly used in aerospace and high-temperature engineering applications due to its outstanding high-temperature strength and oxidation resistance
