16Mo3 vs P265GH: 66% composition overlap. Moderate differences, generally not direct substitutes.
16Mo3 vs P265GH
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.
P265GH
1.0425
Unalloyed pressure vessel steel — THE standard boiler plate material in Europe. ReH >=265 MPa, good weldability, guaranteed elevated-temperature properties to ~450°C. "GH" = suitable for use at elevated temperatures. Used for boilers, pressure vessels, heat exchangers, and steam drums per EN 10028-2 and PED 2014/68/EU.
