Haynes 188 is a cobalt-based heat-resistant alloy, containing about 40% cobalt for excellent temperature stability and magnetic properties. The alloy also includes approximately 22% nickel and chromium, along with around 15% tungsten. This composition provides outstanding oxidation resistance up to 1100°C and makes it suitable for use in environments containing sulphur. Haynes 188 offers good ductility, strong corrosion resistance, and is resistant to wear and impact. Although it cannot be age-hardened, it is highly suitable for cold forming processes.
