11SMnPb30 vs S460NL
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.
S460NL
1.8903
High-strength normalized fine-grain structural steel with 460 MPa yield and impact testing at -50°C. The highest-strength grade in the EN 10025-3 normalized series. Used for offshore platforms, wind turbine towers, arctic bridges, cranes, and heavy steel structures in cold climates.
