Alloy 230 is a nickel-chromium-tungsten-molybdenum alloy which combines excellent high temperature strength, oxidation resistance (up to 2100°F), nitriding resistance and long term stability. It is particularly effective for very long-term applications at temperatures of 1200°F (649°C) or more and is capable of outlasting stainless steels and nickel alloys by as much as 100 to 1 depending upon the temperature.Alloy 230 is a solid-solution-strengthened material which combines excellent high-temperature strength with good fabricability at room temperature.
