Characteristic as below：

• Haynes 230 is a nickel-chromium-tungsten-molybdenum alloy that combines excellent high-temperature strength and oxidation resistance with very good long-term thermal stability and good fabricability.

• Processing conditions and application:

• The alloy is used in gas-turbine engines, in high-temperature heat-treatment equipment and in severe chemical processing industries.

Designed to combine excellent high temperature strength, oxidation resistance (up to 2100°F), nitriding resistance and long term stability. Alloy 230 is a solid solution strengthened material combining excellent high temperature strength with good room temperature machinability. It is especially effective for long-term applications at 1200 °F (649 °C) or higher and, depending on temperature, outlasts stainless steel and nickel alloys by a factor of 100 to 1.
