Alloy 188 is a cobalt-nickel-chromium-tungsten super alloy that is sold under different brand names including: Nickel Alloy 188, Haynes® 188, Udimet 188®. Due to its high level of chromium mixed with small amounts of lanthanum, Alloy 188 can be used to create products that are incredibly tough and corrosion resistant.
Alloy 188 provides an excellent high-temperature strength, suflidation resistance, and good oxidation resistance up to 2000 °F (1095°C). Fabrication is not difficult with Alloy 188, and it can be cold and hot worked, and offers users outstanding ductility and metallurgical stability.
Alloy 188 is also well suited for welding, methods such TIG, MIG, electron beam, and resistance welding.
