Case-hardened steel | C10E - 16MnCr5
The case-hardening steels with carbon contents of less than 0.22 % are intended for case-hardening for components subject to wear. In case hardening, the surface is enriched with carbon to about 0.8 %, then hardened and tempered. The components have a hard, wear-resistant surface layer and at the same time a tough core, which is able to absorb impact stresses without breaking. At the same time, the fatigue strength of the material is increased.
Case-hardened steels are used in a wide range of applications in general mechanical engineering, plant construction and vehicle construction, including gear parts.
Hot-rolled case-hardening steels are listed in DIN EN ISO 683-3 (formerly DIN EN 10084). In practice, the case-hardening steels C10E and C15E 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 in pickled or unpickled.
