11L17 Carbon Steel Bars
1117 is a low carbon, high manganese steel. Machinability is improved over 1018, and case hardening is deep and uniform, supported by a tough ductile core. 1117 is a resulphurized steel with superior case hardening characteristics.
Low-carbon
steels (AISI 1005-1026, 1108-1119, 1211-1215, and 1513-1527 ), by definition,
contains less carbon than other steels and are inherently easier to cold-form
due to their soft and ductile nature.
When strength is not a major concern, low-carbon steels are good choices because they are easy to handle (draw, bend, punch, swage, etc.) and fairly inexpensive. Surface hardness can be improved by a process called carburizing which involves heating the alloys in a carbon-rich atmosphere. Low-carbon steels that are usually carburized are AISI 1015, 1018, 1020, and 1117.
