Esta aleaci\u00f3n al cromo-molibdeno destaca por ofrecer una excelente combinaci\u00f3n de gran dureza y buena resistencia al desgaste. Adem\u00e1s, proporciona una protecci\u00f3n contra la corrosi\u00f3n mejorada frente a otros grados martens\u00edticos con menor contenido de cromo.<\/p>\n<p>Asimismo, el <strong>EN 1.4122<\/strong> contiene aproximadamente un 17% de cromo junto con adiciones de molibdeno. Por esta raz\u00f3n, resulta especialmente id\u00f3neo para entornos ligeramente agresivos con bajo nivel de cloruros. Por otro lado, este acero se endurece mediante tratamiento t\u00e9rmico de templado y revenido. En consecuencia, alcanza una dureza considerable mientras mantiene una tenacidad aceptable. De igual forma, se mantiene magn\u00e9tico en todas las condiciones.<\/p>\n<p>Debido a su gran versatilidad entre propiedades mec\u00e1nicas y resistencia qu\u00edmica, la utilizaci\u00f3n de este material es muy com\u00fan en ingenier\u00eda.
