Banana Diagram Evolves: Welcome the New Global Formability Diagram

December 9, 2021

Global-Formability-Diagram-SteelBubble chart. Banana diagram. Steel strength ductility diagram—it’s been called a lot of things over the years. Now, the chart plotting steel tensile strength vs. elongation has been updated by WorldAutoSteel with new 3rd Gen advanced high-strength grades filling the upper right portion.  

As a result, the organization says in a recent blog post, “perhaps it is more accurate to describe this as the football diagram, as the options now start to fall into the shape of an American or Rugby Football.”

Officially, it is known as the steel Global Formability Diagram (GFD). Download the updated GFD, as well as definitions of all of the latest steel classifications, here.
