ALLOY 400       ESPECIFICAÇÕES TÉCNICAS

Alloy 400 is a ductile nickel-copper alloy with resistance to a wide range of corrosive environments. This grade is often chosen to handle sulfuric acid through 80% concentration at room temperature, and about 15% H2SO2 boiling. Alloy 400 possesses useful resistance to aerated hydrochloric acid up to 10% concentration at room temperature. The alloy has excellent resistance to sea or brackish water under high-velocity conditions. Alloy 400 is one of the few materials with good resistance to hydrofluoric acid.
