Material Description
1.1191 / C45E is a medium-carbon steel commonly supplied hot rolled, untreated or normalized. In its normal machining condition it works very well with general-purpose tools; sharper geometries, including many geometries used for stainless steels, can also perform well, while tools intended for high-strength steels are normally unnecessary. C45E can be quenched and tempered or surface hardened by induction or flame hardening, so always check the actual condition before machining — once hardened, the appropriate tools and cutting conditions must be selected according to the resulting hardness.
