11L17 Carbon Round Bar Stock

11L17 Carbon has excellent carburizing properties.

11L17 Carbon

11L17 is re-sulfurized steel with a good surface finish and machinable to a high degree of precision.

The procedure is the same as for 12L14—only, except that the steel does not alloy with the lead during the process. Moreover, this steel grade contains a high proportion of manganese and a low proportion of carbon. It has nearly all machining characteristics, but its mechanical properties are significantly improved. Aside from that, this steel has excellent carburizing properties.

Machinability and other Processes

The addition of lead improves the machinability of 11L17 when compared to 1117. At the same time, increased hardenability results from the manganese content. During the machining process, lead is only retained in its elemental state, and it disperses within the steel’s structure, allowing the chips to break off more easily.

Besides being used in automatic screw machines, cold finished 11L17 Carbon bars are also commonly used in other types of fabrication. This demand is driven by the size accuracy, finish, straightness, and roundness of cold drawn bars and their energy-saving characteristics.


Pins, gears, shafts, pinions, studs, and joints are the typical applications of 11L17 Carbon. It is also a beneficial material in the automotive and aerospace industries.
