Boro (B):<\/td>0.001% – 0.005%<\/td><\/tr><\/tbody><\/table><\/figure>
Seus recursos incluem:<\/h5>
  • Alta resist\u00eancia e alta resist\u00eancia ao desgaste:<\/strong> Devido \u00e0 adi\u00e7\u00e3o de boro, o 35MnBH tem excelente temperabilidade, o que melhora significativamente a dureza e a resist\u00eancia ao desgaste do material.<\/li>\n\n
  • Boa usinabilidade:<\/strong> Apesar de sua alta dureza, o 35MnBH ainda apresenta bom desempenho de corte e soldagem.<\/li>\n\n
  • Forte resist\u00eancia ao impacto:<\/strong> Adequado para uso sob condi\u00e7\u00f5es de carga de alto impacto.<\/li><\/ul>

    An\u00e1lise de material de a\u00e7o 40Mn2<\/h2>

    40Mn2 \u00e9 outro a\u00e7o de liga de m\u00e9dio carbono comum, e seus principais componentes s\u00e3o:<\/p>

    Elemento<\/strong><\/td>Faixa de conte\u00fado<\/strong><\/td><\/tr>
    Carbono (C):<\/td>0.37% – 0.45%<\/td><\/tr>

    Sil\u00edcio (Si):<\/td>0.15% – 0.35%<\/td><\/tr><\/tbody><\/table><\/figure>
    Suas caracter\u00edsticas incluem:<\/h5>
    • Alta tenacidade e alta resist\u00eancia: <\/strong>O alto teor de mangan\u00eas faz com que o 40Mn2 tenha maior resist\u00eancia e tenacidade.<\/li>\n\n
    • Boa temperabilidade:<\/strong> Ap\u00f3s t\u00eampera e revenimento, o 40Mn2 pode obter excelentes propriedades mec\u00e2nicas abrangentes.<\/li>\n\n
    • Resist\u00eancia \u00e0 corros\u00e3o:<\/strong> Comparado com o a\u00e7o carbono comum, o 40Mn2 tem melhor resist\u00eancia \u00e0 corros\u00e3o.<\/li><\/ul>

      A principal diferen\u00e7a entre 35MnBH e 40Mn2<\/h2>

      Dureza e tenacidade:<\/h5>
      • Devido \u00e0 presen\u00e7a de boro, o 35MnBH tem maior dureza e resist\u00eancia ao desgaste, o que \u00e9 adequado para aplica\u00e7\u00f5es de alto desgaste.<\/li>\n\n
      • 40Mn2 tem maior tenacidade e pode suportar melhor cargas de impacto.<\/li><\/ul>
        Resist\u00eancia ao desgaste:<\/h5>
        • 35MnBH \u00e9 superior ao 40Mn2 e \u00e9 mais adequado para pe\u00e7as que precisam ficar em contato com solo duro por muito tempo.<\/li><\/ul>
          Ambiente aplic\u00e1vel:<\/h5>
          • 35MnBH \u00e9 adequado para ambientes de alto desgaste e alta carga, como minera\u00e7\u00e3o.<\/li>\n\n
          • 40Mn2 \u00e9 mais adequado para aplica\u00e7\u00f5es de carga m\u00e9dia que exigem certa tenacidade, como terraplenagem.<\/li><\/ul>
            \"Corrente<\/figure>
            Corrente de esteira:<\/h5>
            • 35MnBH:<\/strong> Devido \u00e0 sua alta resist\u00eancia ao desgaste e dureza, o 35MnBH \u00e9 muito adequado como material principal da corrente de esteira, o que pode aumentar significativamente a vida \u00fatil da corrente, especialmente em ambientes adversos.<\/li>\n\n
            • 40Mn2:<\/strong> Sua alta tenacidade o torna adequado para componentes de corrente que precisam suportar altas for\u00e7as de impacto, o que pode reduzir o risco de quebra da corrente.<\/li><\/ul>
              Montagem de trilhos:<\/h5>
              • 35MnBH:<\/strong> No conjunto da esteira, componentes-chave como elos e pinos da esteira geralmente usam 35MnBH para melhorar a resist\u00eancia ao desgaste.<\/li>\n\n
              • 40Mn2:<\/strong> Adequado para pe\u00e7as que exigem maior resist\u00eancia, como rodas dentadas de suporte de carga ou rodas motrizes.<\/li><\/ul>

                Vantagens dos dois materiais<\/h2>

                Vantagens do 35MnBH:<\/h5>
                • Alta resist\u00eancia ao desgaste \u00e9 adequada para condi\u00e7\u00f5es de trabalho adversas e reduz a frequ\u00eancia de substitui\u00e7\u00e3o.<\/li>\n\n
                • Excelente desempenho de processamento, adequado para uma variedade de necessidades de fabrica\u00e7\u00e3o.<\/li><\/ul>
