El Q235 es un acero estructural al carbono muy utilizado en China, especificado por la norma nacional GB\/T 700-2006. La designaci\u00f3n \"Q\" significa l\u00edmite el\u00e1stico, y \"235\" se refiere a su l\u00edmite el\u00e1stico m\u00ednimo de 235 MPa (para espesor \u2264 16 mm). Tambi\u00e9n se conoce como acero dulce o chapa de acero com\u00fan, con excelente capacidad de soldadura, capacidad de conformado y rentabilidad, lo que lo convierte en el material m\u00e1s com\u00fan en construcci\u00f3n, maquinaria e ingenier\u00eda general. Es equivalente a ASTM A36 (EE.UU.) y S235JR (Europa) en las normas internacionales.<\/p>\n\n

    \n
  1. Clasificaci\u00f3n (grados de calidad)<\/strong><\/li>\n<\/ol>\n

    El Q235 se divide en cuatro grados de calidad en funci\u00f3n de su composici\u00f3n qu\u00edmica y su resistencia al impacto, con una pureza y una tenacidad crecientes de la A a la D:<\/p>\n

      \n
    • Q235A: No requiere ensayo de impacto; mayor contenido de S; adecuado para estructuras est\u00e1ticas no cr\u00edticas.<\/li>\n
    • Q235B: Ensayo de impacto a 20\u00b0C (\u226527 J); el m\u00e1s utilizado para aplicaciones estructurales generales.<\/li>\n
    • Q235C: Ensayo de impacto a 0\u00b0C (\u226527 J); menor contenido de S\/P; para ambientes fr\u00edos.<\/li>\n
    • Q235D: Ensayo de impacto a -20\u00b0C (\u226527 J); menor contenido de S\/P; para fr\u00edo extremo y estructuras cr\u00edticas.<\/li>\n<\/ul>\n
        \n
      1. Caracter\u00edsticas principales<\/strong><\/li>\n<\/ol>\n
          \n
        • Composici\u00f3n qu\u00edmica: Bajo contenido en carbono (\u226422%), Mn moderado, bajo S\/P; buena soldabilidad y mecanizabilidad.<\/li>\n
        • Propiedades mec\u00e1nicas: Resistencia y ductilidad equilibradas; el l\u00edmite el\u00e1stico disminuye al aumentar el espesor.<\/li>\n
        • Propiedades f\u00edsicas: Alta densidad, m\u00f3dulo el\u00e1stico est\u00e1ndar y buena conductividad t\u00e9rmica.<\/li>\n
        • Procesamiento: F\u00e1cil de cortar, doblar, soldar y mecanizar; apto para laminado en caliente y conformado en fr\u00edo.<\/li>\n<\/ul>\n
            \n
          1. Principales aplicaciones<\/strong><\/li>\n<\/ol>\n
              \n
            • Construcci\u00f3n: Estructuras de acero, vigas, columnas, andamios, componentes de puentes.<\/li>\n
            • Maquinaria: Piezas generales, chasis, soportes, engranajes y recipientes a presi\u00f3n.<\/li>\n
            • Transportes: Bastidores de veh\u00edculos, cascos de barcos y componentes ferroviarios.<\/li>\n
            • Otros: Tuber\u00edas, tanques de almacenamiento y estructuras de ingenier\u00eda en general.<\/li>\n<\/ul>\n
