Haynes 188 is a cobalt-based, heat-resistant alloy containing around 40% cobalt, which imparts high temperature stability and good magnetic properties. The alloy, also known as 2.4683, includes approximately 22% nickel and chromium, as well as about 15% tungsten. This combination offers outstanding oxidation resistance at temperatures up to 1100°C, and makes the material suitable for use in environments containing sulphur. Haynes 188 is notable for its excellent ductility, corrosion resistance, and strong resistance to abrasion and impact. Although it cannot be age-hardened, it is well-suited for cold forming processes.
