What is Haynes 188 Bars and Rods?

Haynes 188 is a cobalt-nickel-chromium alloy strengthened by tungsten and fortified with lanthanum. It is specially formulated to maintain its impressive tensile and creep strength at extreme temperatures, up to 2000°F, while also offering excellent resistance to oxidation. This combination ensures it remains durable and reliable in environments where other materials would quickly fail, making it a standout choice for high-stress applications.
