HAYNES 188 Alloy is a solidsolution-strengthened material which combines excellent high temperature strength with good tabricability at room temperature. It is particularly effective for very long-term applications at temperatures of 1200°F (650°C) or more. In addition, Haynes 188 has excellent high temperature strength and great oxidation resistance up to 2000° F (1095°C).
