Abstract
CHAPA DE AÇO PARA UMA CHAPA DE AÇO ELÉTRICO NÃO ORIENTADO. É provida uma chapa de aço para uma chapa de aço eletromagnético não orientado, que contém 0,0040% ou menos de C, 1,9-3,5% de Si, 0,10-3,0% de Al, 0,10-2,0% de Mn, 0,09% ou menos de P, 0,005% ou menos de S, 0,0040% ou menos de N e 0,0060% ou menos de B, com o restante compreendendo Fe e impurezas. A taxa de recristalização é menor que 50% em uma estrutura de seção transversal na direção da espessura da chapa nas posições de 10 mm em direção ao centro da largura da chapa de ambas as bordas na direção da largura da chapa. Se W denota a largura da chapa, a razão de recristalização é de 50% ou mais em uma estrutura de seção transversal na direção da espessura da chapa em posições correspondentes a 1/4W de ambas as bordas na direção da largura da chapa.
