C22E vs S235J0: 38% composition overlap. Significantly different materials serving different application areas.
C22E vs S235J0
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.
S235J0
1.0114
Basic structural steel with guaranteed Charpy impact at 0°C (KV >=27J). Better low-temperature toughness than S235JR (which only guarantees 27J at +20°C). Same strength class (ReH >=235 MPa). Used for general structural applications in moderate climates: building frames, bridges, storage tanks, and platforms. Very widely available and cost-effective.
