Resistencia al reblandecimiento del acero para herramientas de trabajo en caliente<\/h1>\n\n\n\n

C\u00f3mo cuatro aceros para herramientas de trabajo en caliente — H13, H21, H23 y H26 — mantienen su dureza despu\u00e9s de 100 horas a temperaturas de 480 a 760 °C. Estos son los datos de “resistencia al revenido” que respaldan la vida \u00fatil de las matrices de trabajo en caliente: cu\u00e1nta dureza retiene una matriz durante una exposici\u00f3n prolongada al metal caliente.<\/p>\n\n\n\n
