La fuerza aplicada depende de la escala utilizada.<\/li>\n\n\n\n<li><strong>Liberaci\u00f3n de la carga principal<\/strong>: Se retira la carga principal y se mide la profundidad de la indentaci\u00f3n. Cuanto mayor sea la profundidad de la indentaci\u00f3n, m\u00e1s blando ser\u00e1 el material, y cuanto menor sea la profundidad, m\u00e1s duro ser\u00e1 el material.<\/li>\n<\/ol>\n\n\n\n<p>El valor de dureza Rockwell se calcula como la diferencia de profundidad de indentaci\u00f3n bajo las cargas menor y mayor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-formula-for-rockwell-hardness\">F\u00f3rmula para la dureza Rockwell<\/h3>\n\n\n\n<p>La f\u00f3rmula utilizada para calcular la dureza Rockwell es HR=EFHR = \\frac{E}{F}HR=FE<\/p>\n\n\n\n<p>D\u00f3nde:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>RRHH<\/strong> = N\u00famero de dureza Rockwell<\/li>\n\n\n\n<li><strong>E<\/strong> = Profundidad de la indentaci\u00f3n (medida en micr\u00f3metros o pulgadas)<\/li>\n\n\n\n<li><strong>F<\/strong> = Fuerza aplicada (medida en kgf o N)<\/li>\n<\/ul>\n\n\n\n<p>El valor resultante se utiliza en una escala espec\u00edfica, como HRC, HRB o HRF.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-types-of-rockwell-hardness-scales\">Tipos de escalas de dureza Rockwell<\/h2>\n\n\n\n<p>El ensayo de dureza Rockwell utiliza varias escalas diferentes, en funci\u00f3n del material y de los requisitos del ensayo.
