Abstract
Se proporciona una placa de acero resistente a la abrasión excelente en la resistencia a la abrasión y capacidad de trabajo de doblado a lo ancho. Una placa de acero resistente a la abrasión comprende una composición química específica, donde una fracción en volumen de martensita a una profundidad de 1 mm desde la superficie de la placa de acero resistente a la abrasión es 90% o más, la dureza a una profundidad de 1 mm desde la superficie es 500 HBW 10/3000 a 650 HBW 10/3000 en la dureza de Brinell y una diferencia de dureza en la dirección transversal es 30Hv10 o menos en la dureza de Vickers, siendo la diferencia de dureza en la dirección transversal definida como una diferencia en la dureza a una profundidad de 1 mm desde la superficie entre dos puntos adyacentes a intervalos de 10 mm en una dirección transversal de la placa de acero resistente a la abrasión.
