Nickel Alloy 230 /Haynes 230®
Technical Data Sheet
Alloy 230 is a nickel-chromium-tungsten-molybdenum alloy that combines excellent high temperature strength, outstanding resistance to nitriding environments and excellent long term thermal stability. Alloy 230 is easily fabricated and has very good forming and welding characteristics. Due to Alloy 230 combined properties it is very well suited to a wide variety of component applications in the aerospace and power industries. Alloy 230 is used for combustion cans, transition ducts, flame holders, thermocouple sheaths and other important gas turbine components. Haynes alloy 230 is solution treated at 2150 to 2275°F followed by rapid cooling, and is supplied in this condition (as per AMS 5891 and AMS 5878). Alloy 230 can be both hot worked and cold worked and all parts should be annealed and rapidly cooled in order to restore the best balance of properties.
