Abstract
Se describen en la presente tiras delgadas de metal que tienen superficies laterales exteriores laminadas en caliente caracterizadas por estar principalmente o sustancialmente libres de todos los límites de grano de austenita anteriores o al menos principalmente o sustancialmente libres de todos los límites de grano de austenita anteriores y que incluyen una estructura de superficie alargada. Como resultado, debido a que los límites de grano de austenita anteriores no están principalmente o sustancialmente presentes, todos esos límites de grano de austenita anteriores no son susceptibles al grabado del límite de grano debido al grabo con ácido o decapado. En ejemplos particulares, las tiras delgadas de metal se someten a laminación en caliente con un coeficiente de fricción igual a o mayor que 0.25 con o sin el uso de lubricación.
