Cobalt Round Bar is used in super alloys and in making magnets. The cobalt alloys are used because they are ferromagnetic in nature. The material can maintain its strength even at elevated temperatures. Navstar Steel is a leading manufacturer of the Alloy Stellite 6B Rod and other types in various dimensions.
The material has high wear and tear resistance as well. The bars range from 0.201 inches to 4 inches in diameter. There are also Chrome Moly 1537 Flat Bar types used in various industries. The material can perform at high temperatures exceeding 1000 degrees Celsius and the chemical composition can have chromium, tungsten, nickel, iron, manganese, silicon, carbon, phosphorus and sulfur in the composition.
The ASTM B473 Cobalt Bar Price is higher than that of the lower alloy components. The material has melting range of 1300 degrees Celsius to 1330 degrees Celsius. It also has high thermal conductivity. There are different types of finishes such as the Cobalt Alloy UNS R30188 Bright Bar and the black bars. The tensile strength of the material is high with minimum 862MPa and 310MPa minimum yield strength. The rupture strength decreases with the operating temperatures and the material can operate at above 982 degrees Celsius as well. Please contact us for more information on the Hot Rolled Cobalt Alloy Round Bars and the pricing.
