C10E vs S355J2
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.
S355J2
1.0577
High-strength structural steel with impact testing at -20°C (J2). Higher toughness than S355JR (tested at +20°C). Used for bridges, crane structures, offshore platforms, and cold-weather applications where impact toughness at sub-zero temperatures is required.
