Reference.

INCOLOY® series alloys 800, invented by Special Metals Corporation Group of Companies, is the result of years of monitoring and maintaining chemical properties of the final high temperature strength and oxidation resistance, carburization and other high temperature corrosion. Each refinement of the above, these alloys have established industry standard in high temperature applications requiring optimal creep properties and breaking.

Composition.

This nickel-iron-chromium 800 was introduced in the market in the 1950s to fill the need for alloying heat and corrosion resistant with a relatively low nickel from nickel was, then, designated a ‘strategic’ metal. During the last forty years it has been widely used for its high temperature resistance and its ability to resist oxidation, carburization, and other types of high temperature corrosion.

Applications.

Applications include furnace components and equipment, petrochemical cracking furnace tubes, braids and headers and coating for electric heating elements.
