Carbon Steel AISI 12L14 is a cold finished carbon steel typically offered in Round Bar. The material is a low friction metal that maintains a smooth, machined surface that allows for increased tool life. 12L14 carbon steel is recommended for manufacturing high-speed automatic screw machine parts, is re-sulfurized and re-phosphorized, which provides benefits from the addition of tiny lead particles, providing enhanced machinability. Although 12L14 CF Bar provides excellent machinability, the added lead content reduces the overall strength of the alloy.
