Abstract
A method of producing a steel foam component includes providing a mold defining a cavity. The method also includes positioning an insert within the cavity of the mold. The insert can be configured to form a generally uniform pattern of pores within the steel foam component, and in some cases occupies at least 20% of the cavity. The method can further include pouring molten steel into the cavity, cooling the molten steel into the steel foam component, and removing the steel foam component and the insert from the mold. Steel components having internal shapes corresponding to the insert(s) are also provided.

A steel foam component comprising:
- a steel body having a plurality of pores, the plurality of pores forming a generally uniform pattern throughout the body and occupying at least 20 percent of a volume of the body.
An insert for use with a mold for creating a steel foam component, the insert comprising:
- a 3D-printed body including a plurality of interconnected cores, the 3D-printed body being configured to be positioned within the mold to form the steel foam component having a desired density that is less than a solid steel component.
A steel foam component comprising:
- a steel body including a first section and a second section, the first section having a first density, the second section having a plurality of pores forming a pattern within the body, the second section having a second density that is less than the first density.
