Mais importante ainda, a tecnologia tradicional n\u00e3o consegue produzir excelentes tubos laminados a quente e com acabamento. Como a China tem adotado a tecnologia tradicional por um longo per\u00edodo, ainda h\u00e1 alguns espa\u00e7os em branco em nossos mercados de a\u00e7o inoxid\u00e1vel. Por exemplo, em algumas circunst\u00e2ncias, s\u00e3o necess\u00e1rios tubos laminados a quente. No entanto, o cliente s\u00f3 pode optar por usar tubos de precis\u00e3o trefilados a frio em vez de tubos a quente, pois n\u00e3o pode produzi-los.<\/p>\n<p><!-- \/wp:paragraph --><\/p>\n<p><!-- wp:paragraph --><\/p>\n<p>De acordo com estat\u00edsticas fornecidas pelos Estados Unidos, o mercado de tubos laminados a quente representa 67% em seu mercado de tubos de a\u00e7o inoxid\u00e1vel, e o tubo laminado a frio estirado a frio representa apenas 33%. Isto significa que ainda h\u00e1 67% de n\u00f3s ainda usando um a frio para substituir o a quente, o que aumenta o custo dos tubos de a\u00e7o inoxid\u00e1vel. Al\u00e9m disso, para alguns tubos especiais de a\u00e7o inoxid\u00e1vel com alta liga, alto desempenho, baixa plasticidade e altos requisitos de n\u00edquel, os clientes dir\u00e3o que devem utilizar tubos de tarugos extrudados.
