Se distingue por su mayor contenido de molibdeno (generalmente entre 3-4%), lo que le confiere una resistencia excepcional contra la corrosi\u00f3n por picaduras y en rendija, especialmente en entornos con cloruros y \u00e1cidos agresivos como el sulf\u00farico. El AISI 317L es ideal para aplicaciones que requieren una durabilidad extrema y un alto rendimiento en las condiciones m\u00e1s exigentes.<\/p>\n<p>Gracias a su excelente comportamiento frente a qu\u00edmicos agresivos, el uso de AISI 317L resulta indispensable en sistemas de desulfuraci\u00f3n y plantas petroqu\u00edmicas avanzadas.
