Haynes 188 is a heat-resistant cobalt-based alloy, containing about 40% cobalt, which provides outstanding temperature stability and magnetic conductivity. It also contains approximately 22% nickel and chromium, as well as 15% tungsten. This material stands out for its excellent resistance to oxidation at temperatures up to 1100°C, and it performs well in sulfur-containing environments. Haynes 188 features good ductility, strong corrosion resistance, and excellent resistance to abrasion and impact. The alloy is not age-hardenable but offers excellent cold formability.
