16Mo3 vs P235GH: 66% composition overlap. Moderate differences, generally not direct substitutes.
16Mo3 vs P235GH
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.
P235GH
1.0345
Lowest-strength pressure vessel steel — ReH >=235 MPa. Excellent weldability due to very low C (max 0.16%). THE entry-level boiler/pressure vessel plate in EN 10028-2. Used for low-pressure vessels, boiler drums, heat exchangers, and steam piping at modest pressures and temperatures to ~400°C.
