Originally developed for woven wire furnace conveyor belts, Incoloy DS is now widely used in a variety of heat treatment applications. Its strength and high temperature corrosion resistance make it suitable for light sections. The alloys used in high temperature processes must be able to withstand exposure to high temperature combustion gases and operating environment for a considerable period of time without loss of effective section due to corrosion. Incoloy DS alloy, like other heat-resistant alloys from specialized metal manufacturers, forms a tightly adhered oxide film that protects its surface from corrosion. It also exhibits resistance to “green rust” formation. When atmospheric conditions fluctuate between reduction and oxidation, or in certain cases where the reducing atmosphere contains carburizing properties, green rust may develop in nickel-chromium alloys. Under these conditions, chromium carbides tend to form at grain boundaries and exhibit preferential precipitation.
The density of the alloy is ρ=7.86g/cm³.
