EN 1.0454 (GE270) Cast Non-Alloy Steel

EN 1.0454 cast steel is a carbon steel formulated for casting. Cited properties are appropriate for the normalized and tempered condition. 1.0454 is the EN numeric designation for this material. GE270 is the EN chemical designation.

The graph bars on the material properties cards below compare EN 1.0454 cast steel to: cast carbon 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.
