# EN 1.0501 (C35) Non-Alloy Steel

EN 1.0501 steel is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the normalized condition. 1.0501 is the EN numeric designation for this material. C35 is the EN chemical designation.

It has a moderately low thermal conductivity among the wrought carbon or non-alloy steels in the database.

The graph bars on the material properties cards below compare EN 1.0501 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.
