16Mo3 vs S355ML: 37% composition overlap. Significantly different materials serving different application areas.
16Mo3 vs S355ML
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.
S355ML
1.8834
Thermomechanically rolled fine-grain structural steel — ReH >=355 MPa with Charpy at -50°C (KV >=27J). THE workhorse for large welded steel structures in cold environments. TM rolling = low CEV = excellent weldability even in thick plate. Used for offshore platforms, wind turbine towers, bridges, crane structures, and pressure vessels. Most common TM grade by tonnage.
