C22E vs S700MC
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.
S700MC
1.8974
The highest-strength grade in the EN 10149-2 HSLA series. 700 MPa yield with good cold formability. TMCP for ultra-fine grain structure. Used for telescopic cranes, truck frame rails, dirt-moving equipment, farm equipment, and any application requiring maximum weight reduction in cold-formed steel.
