C35 vs P265GH
Side-by-side chemical composition and mechanical property comparison.
Overview
C35
1.0501
Medium-carbon unalloyed steel with moderate strength. Good machinability and weldability. Used for lightly stressed components like levers, axles, bolts, and general machine parts.
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.
