Anisotropy

In materials science, anisotropy refers to the directional dependence of a material’s physical or mechanical properties. In the rolling mill, as steel is reduced in thickness, its grains are elongated in the direction of rolling. This creates a "texture" where the material might exhibit higher tensile strength in the longitudinal direction compared to the transverse direction. Understanding anisotropy is critical during cold bending, if you bend "with the grain" versus "against the grain," the risk of fracture changes significantly.
