Free-Cutting Steel
11SMnPb30 · 1.0718
Also known as 12L13 / 12L14 (near)
Lead-added free-cutting steel for high-speed automatic machining.
11SMnPb30 (material 1.0718) is a lead-added free-cutting (free-machining) steel designed for high-volume production on automatic lathes. Its sulphur and lead content gives excellent machinability and clean chip breaking. Supplied mainly as cold-drawn (bright) bar for precision turned parts.
