16Mo3 vs S355J0
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.
S355J0
1.0553
Non-alloy structural steel with 355 MPa min yield and 27J impact at 0°C. The "J0" variant between JR (+20°C) and J2 (-20°C). Former designation St52-3U (DIN 17100). Good weldability (CEV ≤0.47). Used for bridges, cranes, buildings, wind turbines, heavy machinery frames, and general structural applications requiring moderate low-temperature toughness.
