Haynes230 High Temperature Alloy Forgings


Haynes230 is a nickel chromium tungsten molybdenum alloy designed to combine excellent high-temperature strength, oxidation resistance (up to 2100 ° F), nitrogen resistance, and long-term stability. Alloy 230 is a solid solution strengthening material with good machinability at room temperature and is particularly suitable for long-term applications at temperatures of 1200 ° F (649 ° C) or higher. Its lifespan can be more than 100 times longer than stainless steel and nickel alloys, depending on temperature conditions.
