C22E vs S355ML: 33% composition overlap. Significantly different materials serving different application areas.
C22E vs S355ML
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.
S355ML
1.8834
Thermomechanically rolled fine-grain structural steel — ReH >=355 MPa with Charpy at -50°C (KV >=27J). THE workhorse for large welded steel structures in cold environments. TM rolling = low CEV = excellent weldability even in thick plate. Used for offshore platforms, wind turbine towers, bridges, crane structures, and pressure vessels. Most common TM grade by tonnage.
