HS 188 is a cobalt-based superalloy containing tungsten, chromium, and nickel, designed for high-temperature structural applications in gas turbines, aerospace engines, and industrial furnaces where service temperatures exceed 1000°C. The alloy offers excellent creep resistance, oxidation resistance, and thermal fatigue performance, with the Solution Treated condition providing optimal balance of strength and ductility for elevated-temperature service.
