P235GH vs P265GH
Side-by-side chemical composition and mechanical property comparison.
Overview
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.
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.
