S460NL vs S355J2: Both fine-grain structural steels — S460NL is a strength class higher
S460NL vs S355J2
Side-by-side chemical composition and mechanical property comparison.
Overview
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.
S355J2
1.0577
High-strength structural steel with impact testing at -20°C (J2). Higher toughness than S355JR (tested at +20°C). Used for bridges, crane structures, offshore platforms, and cold-weather applications where impact toughness at sub-zero temperatures is required.
