C10E vs P355GH
Side-by-side chemical composition and mechanical property comparison.
Overview
C10E
1.1121
Lowest practical carbon case-hardening steel — 0.07-0.13% C. After carburizing: hard surface (HRC 55-60) with extremely soft, tough core (HRC 15-20). Maximum impact absorption. Modern designation for Ck10. Used for pins, bushings, small gears, camshaft lobes, and any carburized part where maximum core toughness and ductility are critical. Also used as cold-heading and deep-drawing wire/strip.
P355GH
1.0473
Higher-strength pressure vessel steel — ReH >=355 MPa, guaranteed elevated-temperature properties. Between P265GH and 16Mo3 in the pressure vessel hierarchy. Used for boilers, steam drums, heat exchangers, and pressure piping operating to ~400°C. EN 10028-2, PED 2014/68/EU compliant. Good weldability.
