11SMnPb30 vs ASTM A588 (Corten)
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.
ASTM A588 (Corten)
High-strength low-alloy weathering steel. Forms a stable protective rust patina eliminating the need for paint. Cu-Cr-Ni-V composition provides 4-8x atmospheric corrosion resistance vs carbon steel. Used for unpainted bridges, architectural facades, sculptures, outdoor structures, and freight cars.
