EN 1.0619 (GP240GH) Cast Non-Alloy Steel

EN 1.0619 steel is a carbon steel formulated for casting. 1.0619 is the EN numeric designation for this material. GP240GH is the EN chemical designation. It has a fairly high base cost and a moderately low tensile strength among cast carbon steels.

The properties of EN 1.0619 steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.0619 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.
