EN 1.1122 (C10E2C) Non-Alloy Steel
EN 1.1122 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.1122 is the EN numeric designation for this material. C10E2C is the EN chemical designation.
It can have a moderately low tensile strength among the wrought carbon or non-alloy steels in the database.
The properties of EN 1.1122 steel include four common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.1122 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.
