INCOLOY® alloy MA956 (UNS S67956), first developed as an aerospace superalloy and now used in a range of industrial applications, combines excellent strength and fabricability with outstanding resistance to prolonged exposure up to 1300°C (2400°F). Its exceptional properties result from the mechanical alloying process by which it is made; a process which allows a fine distribution of yttrium oxide particles to be incorporated into a highly corrosion-resistant Fe-Cr-Al alloy.

The alloy has excellent oxidation resistance up to 1300°C (2400°F) and significant creep strength up to its unusually high melting point of 1482°C (2700°F). Thicker sections may be used up to 1370°C (2500°F). Typical industrial applications include hearth rollers, radiant tubes, furnace muffles, fluidized bed retorts, heat treatment baskets, mesh belts, heat shields, burner nozzles, sensor tubes for thermowells and combustion chamber components for diesel engines.

A full range of both hot and cold-worked mill products is available. The forming and machining characteristics are similar to those of conventional high-chromium ferritic steels and Fe-Cr-Al alloys.
