Haynes 188 alloy is often referred to by other trade names such as Alloy 188, Udimet 188, and Conicro 4023. Haynes 188 is a cobalt-nickel-chromium-tungsten alloy that may be readily fabricated for aerospace and commercial gas turbine engine applications, including combustion cans, flame holders, liners, transition ducts, and afterburner parts. Haynes 188 alloy also combines excellent high-temperature strength with very good resistance to oxidizing environments up to 2000°F (1095°C).

Other features include superior resistance to molten chloride salts and resistance to gaseous sulfidation.
