11SMnPb30 vs S355J0
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.
S355J0
1.0553
Non-alloy structural steel with 355 MPa min yield and 27J impact at 0°C. The "J0" variant between JR (+20°C) and J2 (-20°C). Former designation St52-3U (DIN 17100). Good weldability (CEV ≤0.47). Used for bridges, cranes, buildings, wind turbines, heavy machinery frames, and general structural applications requiring moderate low-temperature toughness.
