EN 1.1165 (G28Mn6) Cast Non-Alloy Steel

EN 1.1165 cast steel is a carbon steel formulated for casting. 1.1165 is the EN numeric designation for this material. G28Mn6 is the EN chemical designation. It can have the lowest ductility and the highest tensile strength among cast carbon steels.

The properties of EN 1.1165 cast steel include three 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 1.1165 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.
