La aleación 200/201 es extremadamente resistente a los álcalis cáusticos, incluso en estado fundido. El contenido de carbono extra-bajo de la aleación 200/201 le aporta una inmunidad virtual al ataque intergranular por encima de los 315 °C. La presencia de cloratos debe mantenerse al mínimo, ya que aceleran la tasa de ataque.
