\u00a0 \u00a0 \u00a0 A Hastelloy B3 (N10675) \u00e9 uma liga de alta temperatura \u00e0 base de n\u00edquel composta por n\u00edquel, molibd\u00e9nio, cobalto e outros elementos, com um teor de n\u00edquel de cerca de 65%. O material de liga \u00e0 base de n\u00edquel Hastelloy B3 (N10675) \u00e9 um novo material melhorado com base no Hastelloy B2, que melhora a estabilidade t\u00e9rmica do material, melhorando assim a resist\u00eancia \u00e0 corros\u00e3o e melhorando as propriedades de conforma\u00e7\u00e3o t\u00e9rmica e de conforma\u00e7\u00e3o a frio. Nos \u00faltimos anos, tem sido cada vez mais utilizado na produ\u00e7\u00e3o e fabrico de equipamento qu\u00edmico.<\/span><\/p>\n

4. Carater\u00edsticas dos materiais<\/span><\/strong><\/p>\n

    \n
  • A liga B-3 \u00e9 um novo membro da fam\u00edlia de ligas de n\u00edquel-molibd\u00e9nio, que possui uma excelente resist\u00eancia \u00e0 corros\u00e3o a qualquer temperatura e concentra\u00e7\u00e3o de \u00e1cido clor\u00eddrico. Ao mesmo tempo, tem tamb\u00e9m uma boa resist\u00eancia \u00e0 corros\u00e3o do \u00e1cido sulf\u00farico, \u00e1cido ac\u00e9tico, \u00e1cido f\u00f3rmico, \u00e1cido fosf\u00f3rico e outros meios que n\u00e3o t\u00eam propriedades de oxida\u00e7\u00e3o.<\/span><\/li>\n
  • Devido a ajustamentos na sua composi\u00e7\u00e3o qu\u00edmica, a sua estabilidade t\u00e9rmica foi muito melhorada em compara\u00e7\u00e3o com a liga B-2 original. A liga B-3 tem uma elevada resist\u00eancia \u00e0 corros\u00e3o por pite, \u00e0 corros\u00e3o sob tens\u00e3o, \u00e0 corros\u00e3o da aresta de corte e \u00e0 corros\u00e3o da zona afetada pelo calor da soldadura.<\/span><\/li>\n
  • Estrutura metalogr\u00e1fica da Hastelloy B-3: A Hastelloy B-3 \u00e9 uma estrutura de treli\u00e7a c\u00fabica de face centrada. O teor de ferro e cr\u00f3mio da liga \u00e9 controlado a um valor reduzido, impedindo assim a precipita\u00e7\u00e3o da fase Ni4Mo entre 700-800\u00b0C, reduzindo assim o risco de fragiliza\u00e7\u00e3o por processamento.<\/span><\/li>\n<\/ul>\n

    V. Campos de aplica\u00e7\u00e3o B-3<\/span><\/strong><\/p>\n

    \u00a0 \u00a0 \u00a0 Tem uma vasta gama de aplica\u00e7\u00f5es nos dom\u00ednios da qu\u00edmica, petroqu\u00edmica, fabrico de energia e controlo da polui\u00e7\u00e3o, especialmente em ind\u00fastrias como a do \u00e1cido sulf\u00farico, \u00e1cido clor\u00eddrico, \u00e1cido fosf\u00f3rico e \u00e1cido ac\u00e9tico. No entanto, tal como a liga B-2, a B-3 n\u00e3o \u00e9 recomendada para utiliza\u00e7\u00e3o em ambientes onde existam sais de ferro trivalentes e sais de cobre divalentes, porque estes sais causam rapidamente corros\u00e3o e danos. Quando o \u00e1cido clor\u00eddrico entra em contacto com o ferro e o cobre, reage com eles para formar sais de ferro trivalente e de cobre divalente.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
