P460NH vs S355J2: 73% composition overlap. Some similarities but notable differences in alloying elements.
P460NH vs S355J2
Side-by-side chemical composition and mechanical property comparison.
Overview
P460NH
1.8935
Highest-strength normalized pressure vessel fine-grain steel — ReH >=460 MPa. "N" = normalized, "H" = elevated temperature. Used for high-pressure vessels, boiler drums, and chemical reactors where maximum strength with guaranteed elevated-temperature properties is needed. EN 10028-3 + PED compliant. Good weldability due to fine grain and controlled CEV.
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.
