Tanvir Nickel Alloys, based in Cairo, Egypt, is a trusted manufacturer and supplier of **Haynes 188 bar**, a high-performance cobalt-based alloy designed for the toughest environments. With a focus on heat- and corrosion-resistant alloys, Tanvir delivers top-quality Haynes 188 bars that adhere to strict international standards for aerospace, power generation, and high-temperature industrial applications. Thanks to their precision manufacturing and rigorous quality control, Tanvir Nickel Alloys guarantees that each bar offers exceptional strength, oxidation resistance, and long-lasting durability, making them a reliable partner for advanced engineering needs both in Egypt and around the world.
**Haynes 188 bar** is primarily made of cobalt, with notable amounts of nickel (22%), chromium (22%), and tungsten (14%). This unique blend provides remarkable strength and oxidation resistance at temperatures reaching 1095°C (2000°F), along with excellent fabricability and thermal stability. The bar boasts a tensile strength between 895 and 1035 MPa and maintains impressive creep resistance even under prolonged exposure to high temperatures. Its microstructure also enhances its resistance to sulfidation and carburization, making it an excellent choice for demanding, high-heat environments like gas turbines and combustion chambers.
