P235GH
1.0345Lowest-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.
