HS 188 is a cobalt-based superalloy containing tungsten and chromium, designed for high-temperature structural applications requiring excellent creep resistance and oxidation resistance up to approximately 1100°C. The F (as-fabricated) condition represents the material in its initial wrought state without solution treatment or age hardening, providing baseline mechanical properties suitable for elevated-temperature service in jet engines, gas turbines, and aerospace heat-exchanger components.
