EN 1.1152 (C20E2C) Non-Alloy Steel
EN 1.1152 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. 1.1152 is the EN numeric designation for this material. C20E2C is the EN chemical designation.
The properties of EN 1.1152 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 1.1152 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.
