HAYNES 188 is a cobalt-based superalloy primarily made up of cobalt, chromium, nickel, and tungsten, with a touch of lanthanum to boost oxidation resistance. The chromium in the alloy enhances its protection against corrosion and oxidation, while tungsten plays a key role in maintaining high-temperature strength. The bars and rods made from HAYNES 188 showcase impressive tensile strength, decent ductility, and outstanding creep resistance. This alloy remains mechanically stable even under thermal cycling and extended exposure to high temperatures, making it perfect for tough service conditions that involve intense heat and stress.
