C10E vs C35
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.
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.
