Abstract

"ARTIGO DE AçO". A invenção refere-se a um artigo de aço consistindo de uma liga que contém em %-peso: 1,7-2,5 de C; 0,1-2, 0 de Si; 0,1-2,0 de Mn; no máximo 0,2 de N; no máximo 0,2 de S; 12-16 de Cr; 2,1-3,5 de (Mo + W/2); 5-8 de V; no máximo 0,1 de Nb; de balanço essencialmente apenas ferro e impurezas inevitáveis. O aço apresenta uma micro-estrutura obtenível por uma fabricação do aço que compreende formação por aspersão de um lingote, a micro-estrutura do qual contendo 14-25% em volume de carbetos principalmente do tipo MC, onde M substancialmente consiste de vanádio, carbetos estes que pelo menos 80% em volume apresentam um formato substancialmente arredondado e um tamanho na extensão maior dos carbetos chegando a 1-10 <109>m, e carbetos-M~ 7~C~ 3~, onde M substancialmente consiste de cromo, carbetos estes que tipicamente apresentam um formato mais alongado que os carbetos-MC, carbetos-MC estes que pelo menos 80% em volume apresentam uma extensão máxima chegando a 3-50 <109>m.
