Corrosion resistance

ALLOYX shows excellent oxidation resistance up to 1200 °C (2190 °F) and can also be used in neutral as well as in reducing atmospheres.
ALLOYX is resistant in carburizing and nitriding atmospheres.

Applications

Due to its corrosion resistance in various atmospheres up to very high temperatures, and excellent high-temperaturestrength, ALLOYX finds wide application in hightemperature service.

Typical applications are:
  • • components for industrial and aircraft gas turbines(combustion chambers, honeycombs, housings etc.)
  • • industrial furnace parts, support rolls, grids, wire belts andradiant tubes
  • • pigtails in petrochemical furnaces
  • • high temperature gas cooled nuclear reactors
