What is Haynes 188 Bars and Rods?

Cobalt (39–41%), nickel (20–24%), chromium (21–24%), and tungsten (13–15%) make up Haynes 188 Bars and Rods, with trace amounts of carbon and lanthanum. This high-performance alloy offers superior strength in extremely hot conditions and outstanding oxidation resistance up to 1095°C. It provides good elongation (20–30%), yield strength (400–550 MPa), and tensile strength (850–1000 MPa). Haynes 188 is appropriate for prolonged exposure to harsh, high-temperature environments, especially in thermal processing and aerospace systems, because it retains structural integrity under thermal fatigue and stress.
