Formability is simply the ability of a sheet metal product to be formed into the desired shape reliably and repeatedly using the selected metal grade and stamping system parameters like the forming process, lubrication, die materials, and tool coatings.

Successful forming, especially with advanced materials, requires an understanding of key input variables and their interaction so that the stamping system parameters can be modified if necessary. 

This section provides an overview of how sheet metal flows and highlights issues more important and prevalent with Advanced High-Strength Steels.
