Home > Haynes 188 Bar
Okoye Nickel Alloys is a trusted manufacturer and supplier of Haynes 188 Bars, located in Kinshasa, Congo. They specialize in high-quality cobalt-based alloy products designed for critical engineering applications. Haynes 188 stands out for its remarkable blend of oxidation resistance, strength, and fabricability, even at scorching temperatures of up to 1095°C. This alloy excels in resisting hot corrosion and thermal fatigue, making it perfect for tough environments. Okoye Nickel Alloys offers Haynes 188 bars in various forms, including precision-ground, hot-rolled, and forged, all while adhering to international quality standards and ensuring precise dimensions for aerospace, gas turbine, and industrial furnace components.
Haynes 188 Bars are primarily made up of cobalt (the balance), nickel (22%), chromium (22%), and tungsten (14%), with a touch of lanthanum (0.03%) to boost oxidation resistance. This alloy boasts impressive tensile strength (up to 950 MPa), yield strength (around 450 MPa), and an elongation of about 40%, all while maintaining stability under extreme temperatures. Haynes 188 is known for its exceptional resistance to oxidation, sulfidation, and carburization, along with good weldability and thermal stability. Its fine-grain microstructure contributes to high creep strength and fatigue resistance, making it an excellent choice for applications that involve prolonged exposure to cyclic heating and corrosive gases.
