Hot strip

C10E | 1.1121

The steel grade C10E belongs to the case-hardened steels and is used for construction and mechanical engineering parts with low core strength, such as levers, joints, bushings, bolts, pins, pivots, gears, etc. In practice, the case-hardening steels C10 and C15 have become established alongside 16MnCr5. These steel grades are slit by thyssenkrupp Materials Processing Europe from hot-rolled wide strip to the desired width and supplied pickled or unpickled.
