While SFSA Webinar 3 is foundational for the entire “Informational” and “More Depth” series, this episode is nearly a twin.  The baseline for Castability Geometry is the family of Carbon & Low Alloy steels made in room temperature sand or ceramic molds;  Deviating from that baseline in varying degrees are the High Alloy steels.  Those deviations are grouped among the High Alloy steels in this episode, and how to modify Castability Geometry for each High Alloy group is shown in models and simulations.
