1117 (HR,CF) - Low carbon, high manganese steel. Suitable for bending, broaching and most deformations without cracking. C1117 has high mechanical properties and high machinability. Uniform depth of case hardening. 1117 is best suited for machined parts that must subsequently be carburized. In addition to good surface hardness, the carburized part retains a ductile core. 1117 is ideal for making parts subject to shock or vibration stress. 1117 is available as leaded steel (11L17) in some sizes. Addition of 0.15/.35% lead improves free cutting properties without sacrificing carburizing properties.
