16Mo3 vs S355J2
Side-by-side chemical composition and mechanical property comparison.
Overview
16Mo3
1.5415
Molybdenum-alloyed pressure vessel steel — THE European Mo-Kesselblech. Mo 0.25-0.35% improves creep resistance and elevated-temperature strength to ~500°C (higher than P265GH at ~400°C). Used for superheater tubes, boiler drums, steam piping, and heat exchangers in power generation. EN 10028-2 + PED.
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.
