O aumento do teor de ferrita far\u00e1 com que a tenacidade ao impacto diminua, e tamb\u00e9m causar\u00e1 a precipita\u00e7\u00e3o de nitrog\u00eanio na ferrita, resultando na forma\u00e7\u00e3o de nitreto de cromo, porque o nitrog\u00eanio tem uma solubilidade menor na ferrita do que na austenita.<\/p>\n
O tratamento a frio pode reduzir a resist\u00eancia ao impacto do a\u00e7o inoxid\u00e1vel duplex 2205 e aumentar a temperatura de transi\u00e7\u00e3o d\u00factil-fr\u00e1gil. E o envelhecimento na faixa de 280-350 \u2103 tamb\u00e9m levar\u00e1 \u00e0 redu\u00e7\u00e3o da tenacidade.<\/p>\n
