합금 230 특징:
합금 230은 탁월한 고온 강도, 장기간 노출을 위한 최대 1149℃의 산화 환경에 대한 탁월한 저항성, 질화 환경에 대한 최고의 저항성 및 우수한 장기 열 안정성을 결합합니다. 대부분의 고온 합금보다 열팽창이 낮고 고온에 장기간 노출되어도 결정립이 조대화되는 것에 대한 저항성이 우수합니다.

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 low thermal expansion than most high temperature alloys, and good resistance to grain coarsening with prolonged exposure to high temperatures.
Applications: Gas turbine engine combustion cans, transition ducts, after-burners, flameholders and thermocouple sheaths; high temperature heat exchangers; and industrial furnace heat resistant components.
