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.
S500MC
1.0984
High-strength low-alloy (HSLA) hot-rolled steel for cold forming. Thermomechanically rolled for fine grain structure. 500 MPa yield strength with excellent cold formability. Used for automotive chassis, truck frames, crane booms, and agricultural equipment.
