Ni Cr Fe N08800 Incoloy 800 Wire Nickel Alloy Wire 1,370°C Melting Point For Chemical Industry
Product Introduction
Incoloy 800 wire is an extremely important high-performance material in the chemical industry. Its excellent corrosion resistance enables it to remain stable in a variety of highly corrosive environments, especially in chlorides, low-concentration NaOH aqueous solutions, and high-temperature and high-pressure water, showing excellent resistance to stress corrosion cracking. The main components of this alloy include nickel, chromium, and iron, with a nickel content of about 30-45%, a chromium content of 15-25%, and a small amount of aluminum and titanium. The combination of these elements not only gives Incoloy 800 wire excellent corrosion resistance, but also ensures its stability and mechanical properties at high temperatures through solid solution treatment.
In the manufacture of chemical equipment, Incoloy 800 wire is widely used in the manufacture of reactors, heat exchangers, evaporators and other key components of the connection and support structure. These equipment need to operate for a long time in high temperature, high pressure and corrosive media. The high strength and corrosion resistance of Incoloy 800 wire ensure the reliability and safety of the equipment. In addition, Incoloy 800 wire also has good oxidation resistance and carburization resistance, and can work at high temperatures up to 1500°F (816°C).
