.... Austenitic stainless steels can also develop anisotropy, which while less severe than ferritic steels, can cause “earing,” in which round blanks deform nonuniformly in a four-, six-, or eight-fold symmetry, causing excess ear-shaped material to extend beyond the intended dimensions of the component.
