INCONEL® alloy MA 758 is an oxide-dispersionstrengthened (ODS) nickel-chromium superalloy, made by mechanical alloying. It is a development of the wellestablished aerospace superalloy, INCONEL alloy MA 754, with its chromium content increased to 30%, to improve its performance in corrosive environments at high temperatures. The alloy’s high-temperature strength is enhanced by the use of yttrium oxide for dispersion strengthening.
In addition to its strength and corrosion resistance at high service temperatures, it is readily fabricated and can be hot formed into a range of shaped components for use in thermal processing applications. INCONEL alloy MA 758 is used in some of the most demanding applications for high-temperature metals and alloys. For example, for furnace skid rails to transport heavy steel billets and slabs, at 1260°C(2300°F) and above, and for the bowl-shaped
components used to spin molten glass, at around 1200°C (2200°F), to produce fiberglass for thermalinsulation.
It is used in a range of thermal processing applications, from furnace components, such as hearth rollers, to jigs, tools, and other fabrications for supporting workpieces through heat-treatment processes. It has been specified for a fuel atomizer application in diesel engines.
