Free-Cutting Steel
11SMn30 · 1.0715
Also known as 1212 / 1213 (near)
Lead-free free-cutting steel for high-speed automatic machining.
11SMn30 (material 1.0715) is a sulphur free-cutting (free-machining) steel without lead, designed for high-volume production on automatic lathes. Its sulphur content gives excellent machinability and clean chip breaking. Supplied mainly as cold-drawn (bright) bar.
