La aleación C-4 tiene una excelente estabilidad a altas temperaturas y una excelente resistencia a las grietas por estrés y corrosión y a atmósferas oxidantes de hasta 1040ºC. Tiene una resistencia excepcional a una amplia variedad de entornos de procesos químicos, incluyendo ácidos minerales contaminados en caliente, disolventes, medios contaminados con cloro y cloro (orgánicos e inorgánicos), ácidos fórmicos y acéticos, anhídrido acético, y.
soluciones de agua de mar y salmuera.
