Abstract

trata-se de uma chapa de aço resistente à abrasão que combina resistência a craqueamento por corte de gás e resistência à abrasão com baixo custo. a chapa de aço tem uma composição constituinte que contém, em % em massa, c: 0,10% a 0,23%, si: 0,01% a 1,0%, mn: 0,30% a 3,00%, p: não mais do que 0,025%, s: não mais do que 0,02%, cr: 0,01% a 2,00%, al: 0,001% a 0,100% e n: não mais do que 0,01%, com o saldo sendo composto por fe e impurezas inevitáveis. a chapa de aço tem uma estrutura na qual a porcentagem de volume de martensita em uma profundidade de 1 mm a partir de uma superfície da chapa de aço resistente à abrasão é pelo menos 90%, e o tamanho de grão de austenita anterior no centro na direção de espessura da chapa de aço não excede 80 ¿m. a dureza em uma profundidade de 1 mm a partir da superfície da chapa de aço resistente à abrasão é, na escala brinell, 360 a 490 hbw 10/3.000, e uma concentração de mn [mn] (em % em massa) e uma concentração de p [p] (em % em massa) na área de segregação central na direção de espessura de chapa satisfazem 0,04[mn] + [p] < 0,55.
