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.
P355NL
1.0566
Normalized pressure vessel steel with low-temperature toughness — ReH >=355 MPa, Charpy at -40°C (KV >=27J). "NL" = Normalized + Low-temperature. Used for pressure vessels, storage tanks, and process equipment operating in cold environments (LPG, cryogenic). EN 10028-3 + PED compliant.
