Haynes 230

Principal Design Features

This alloy of nickel-chromium and tungsten is another in the family of high temperature oxidation resistant, high strength alloys. It may be utilized effectively at temperatures up to 2100 F.


Gas turbine hot section components such as combustion cans, thermocouple protection tubes, heat exchangers and industrial furnace fixtures and muffles.


Conventional machining techniques used for iron based alloys may be used. This alloy does work-harden during machining and has higher strength and “gumminess” not typical of steels. Heavy duty machining equipment and tooling should be used to minimize chatter or work-hardening of the alloy ahead of the cutting.
