16Mo3 vs P355GH
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.
P355GH
1.0473
Higher-strength pressure vessel steel — ReH >=355 MPa, guaranteed elevated-temperature properties. Between P265GH and 16Mo3 in the pressure vessel hierarchy. Used for boilers, steam drums, heat exchangers, and pressure piping operating to ~400°C. EN 10028-2, PED 2014/68/EU compliant. Good weldability.
