Side-by-side chemical composition and mechanical property comparison.
Overview
11SMnPb30
1.0718
Leaded free-cutting steel — the highest machinability rating among carbon steels. Pb+S combination gives excellent chip breaking and surface finish. The standard grade for high-volume automatic lathe parts. Used for screws, nuts, bolts, bushings, pins, and automotive turned parts. ≈ AISI 12L14.
S700MC
1.8974
The highest-strength grade in the EN 10149-2 HSLA series. 700 MPa yield with good cold formability. TMCP for ultra-fine grain structure. Used for telescopic cranes, truck frame rails, dirt-moving equipment, farm equipment, and any application requiring maximum weight reduction in cold-formed steel.
