C22E vs S355NL
Side-by-side chemical composition and mechanical property comparison.
Overview
C22E
1.1151
Low-carbon unalloyed steel for case hardening and general engineering — 0.17-0.24% C. After carburizing: surface HRC 55-60, soft tough core. Much cheaper than alloy case-hardening steels (16MnCr5, 20MnCr5). Modern designation for Ck22. Used for pins, bolts, levers, lightly loaded gears, and any carburized part where alloy additions are not justified. Also used as cold-heading wire.
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.
