Hastelloy C-4 Wire Description
Hastelloy C-4 wire is a robust, nickel-chromium-molybdenum alloy that offers outstanding resistance to a wide range of chemical corrosions, including those from oxidizing and reducing agents. It is particularly noted for its stability during high-temperature applications, with excellent resistance to stress-corrosion cracking, pitting, and crevice corrosion. The alloy's composition ensures minimal grain-boundary carbide precipitation during welding, enhancing its suitability for use in the chemical processing industry, where high integrity of welded joints is critical. Hastelloy C-4 wire is commonly used in environments where high temperatures and corrosive chemicals are present, such as in the manufacture of reactors, heat exchangers, and piping systems in the chemical, petrochemical, and pharmaceutical industries.
