11SMn30 vs 11SMnPb30?

Same base chemistry; the Pb version adds 0.20–0.35% lead for still higher cutting speeds and better surface finish. Where lead is restricted (RoHS-sensitive parts), 11SMn30 is the fallback.

1.0715 (11SMn30)

Data verified

11SMn30 (1.0715) is Europe’s standard sulfur free-cutting steel under EN 10087: about 0.30% sulfur and almost no silicon, giving fast, clean chip-breaking on automatic lathes without lead. It is the default EN bar grade for high-volume turned parts.

Properties

Tensile strength	380–510 MPa (delivery-condition dependent)
Machinability	Excellent (reference class for EN free-cutting)
Density	7.85 g/cm³

Heat treatment

Used as-rolled, peeled or cold drawn; the low carbon gives no useful hardening response.

Applications & Processing

Applications: Turned fittings, fasteners, hydraulic connectors, bushings and small shafts across European machining shops.

Processing: Excellent machinability and consistent quality in bright (drawn/peeled) execution; poor weldability; not for structural or pressure duty.
