Haynes® 230 excels in applications requiring strength, oxidation resistance and dimensional stability in prolonged high-temperature environments.
This material may also appear under the following names:
Haynes® 230 is a nickel-chromium-tungsten-molybdenum alloy that combines excellent high-temperature strength, outstanding resistance to oxidizing environments up to 2100°F (1149°C) for prolonged exposures, premier resistance to nitriding environments and excellent long-term thermal stability. It is readily fabricated and formed, and is castable. Other attractive features include lower thermal expansion characteristics than most high-temperature alloys and a pronounced resistance to grain coarsening with prolonged exposure to high temperatures.
The following are Haynes® 230’s chemical constituents according to ASTM standards:
This alloy’s composition meets ASTM standards for UNS N06230. For projects requiring unique material variants or proprietary chemistries, please include the details at the time of inquiry.
Fasteners made with Haynes® 230 alloy perform reliably in demanding industries, such as:
Nickel Systems stocks a comprehensive range of Haynes® 230 fasteners, including:
