Carbon steel 8670 rectangle bar is made from an alloy steel containing chromium, nickel, and molybdenum that provides high strength, toughness, and wear resistance. This makes 8670 rectangle bars suitable for demanding applications like shafts, axles, circular saw blades, and other machined parts requiring good mechanical properties and edge holding ability. The hot rolled and annealed processing enhances the machinability and toughness of these bars. Common uses include components for the lumber industry as well as general industrial machine parts and tools.
