UNS R30605 Bar Forged Bar Round Steel Turned L605 Grinded Rod Haynes 25 Cobalt-Based Alloy

The chemical composition of L605 cobalt-based alloy is mainly composed of cobalt (Co), chromium (Cr), tungsten (W), molybdenum (Mo), nickel (Ni) and other elements. Among them, cobalt, as a matrix element, has a content of more than 50% and is the main source of alloy strength. The addition of chromium significantly improves the 

corrosion resistance and oxidation resistance of the alloy, 

it to maintain stable performance in harsh environments. The addition of tungsten and molybdenum further enhances the high-temperature strength and hardness of the alloy, allowing it to maintain excellent performance at high temperatures. In addition, the alloy also contains a small amount of iron (Fe), manganese (Mn), silicon (Si) and other elements to adjust the mechanical properties and processing properties of the alloy.
