Features
Alloy 230 combines excellent high-temperature strength, outstanding resistance to oxidizing environments up to 1149℃ for prolonged exposure, premier resistance to nitriding environments, and excellent long-term thermal stability. It has lower thermal expansion than most high-temperature alloys and exhibits good resistance to grain coarsening with prolonged exposure to high temperatures.
Applications
Widely used in gas turbine engine combustion cans, transition ducts, after-burners, flameholders, and thermocouple sheaths; high-temperature heat exchangers; and industrial furnace heat-resistant components.
