11SMnPb30 vs S355NL
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.
S355NL
1.0546
Normalized fine-grain structural steel with 355 MPa yield and -50°C impact toughness. The most widely used fine-grain grade in EN 10025-3. Workhorse for offshore, bridges, cranes, and wind turbine towers in cold climates. Better low-temp toughness than S355J2.
