Isis Metals is a well-respected manufacturer and supplier of Haynes 188 Bars and Rods, located in Manila, Philippines. We’re committed to delivering top-notch cobalt-based alloys that are renowned for their exceptional strength at high temperatures and resistance to oxidation. With a strong focus on quality and innovation, we make sure that every Haynes 188 product meets the highest global industry standards for performance and reliability. Our Haynes 188 Bars and Rods are designed to endure extreme conditions, providing outstanding durability, creep resistance, and thermal stability. Serving a diverse array of industrial sectors, Isis Metals has become a trusted partner for demanding applications in aerospace, power, and engineering.
The composition of Haynes 188 Bars and Rods primarily includes cobalt, along with notable amounts of nickel (22%), chromium (22%), tungsten (14%), and trace amounts of lanthanum. This distinctive blend gives the alloy remarkable strength, oxidation resistance, and thermal stability at temperatures reaching up to 1095°C (2000°F). It also shows excellent resistance to carburization and sulfidation while maintaining impressive creep and fatigue properties. With a tensile strength of about 930 MPa and good ductility, Haynes 188 strikes a perfect balance between high-temperature performance and exceptional formability and weldability, making it perfect for tough service conditions.
