C10E vs S355NL
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.
S355NL
1.0546
Normalized fine-grain structural steel with 355 MPa yield and -50°C impact toughness. The most widely used fine-grain grade in EN 10025-3. Workhorse for offshore, bridges, cranes, and wind turbine towers in cold climates. Better low-temp toughness than S355J2.
