EN 1.1219 (C56E2) Induction-Hardening Bearing Steel

EN 1.1219 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.1219 is the EN numeric designation for this material. C56E2 is the EN chemical designation. It can have a fairly high tensile strength among the wrought carbon or non-alloy steels in the database.

The properties of EN 1.1219 steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.1219 steel to: wrought carbon or non-alloy steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
