Material Notes:
INCONEL alloy 693 is a new alloy from Special Metals which offers resistance to high temperature corrosion mechanisms not previously available from a nickel-based alloy. Of particular interest to the designer is the alloy's resistance to metal dusting. INCONEL® alloy 693 offers the best resistance to metal dusting in chemical and petrochemical processing environments of any conventional alloy currently manufactured. Like its predecessor, INCONEL alloy 690, the alloy's high chromium content gives it excellent resistance to oxidation and sulfidation.ApplicationsPetrochemical: Syntheses gas productionWate to Energy and Biomass IncineratorsThermal ProcessingBurner NozzlesHigh-Temperature Fuel Cell ReformersInformation Provided by Special Metals Corporation
