Unalloyed case-hardening steels (e.g. C15R as per EN ISO 683-3) are used in automotive manufacturing and in the general mechanical engineering sector for parts such as hubs, shafts and levers that are subject to relatively low stresses. By carefully controlling their composition, alloyed case-hardening steels (e.g. 16MnCrs5 as per EN ISO 683-3) can be used for the fabrication of components requiring a medium to high level of surface hardness combined with a tough inner core. Examples of this type of component include highly stressed gear wheels and control elements in automotive and aircraft construction. Steeltec’s temperature-controlled rolling process allows us to supply customers with Bosch-compliant 16MnCrS5 steel with an almost pure ferritic-pearlitic microstructure.
