Typical Applications |
For corrosion resistance in the chemical, petrochemical and marine industries, especially in oxidizing environments. |
For corrosion resistance where media are oxidizing to mildly reducing; Palladium-stabilized, superior crevice corrosion resistance. |
For corrosion resistance where media are oxidizing to mildly reducing and where high strength is required. |
