16Mo3 vs S355NL
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.
S355NL
1.0546
Normalized fine-grain structural steel with 355 MPa yield and -50°C impact toughness. The most widely used fine-grain grade in EN 10025-3. Workhorse for offshore, bridges, cranes, and wind turbine towers in cold climates. Better low-temp toughness than S355J2.
