Incoloy DS is a nickel-iron-chromium alloy specifically engineered for high-temperature applications where both oxidation resistance and mechanical strength are required. With its balanced nickel and chromium composition, Incoloy DS provides excellent resistance to carburization, oxidation, and sulfidation at elevated temperatures, making it ideal for use in aggressive furnace and petrochemical environments.
This alloy is commonly used in furnace fixtures, conveyor belts, heat treatment baskets, and petrochemical processing equipment. Its ability to retain strength and resist scaling under cyclic heating conditions ensures long service life in demanding thermal environments. Incoloy DS is typically supplied in the form of sheets, plates, bars, and fabricated components for industrial high-temperature service.
