About Alloy 20
Alloy 20 contains niobium for stabilization which enhances its corrosion resistance. The alloy is an iron-base, austenitic alloy with excellent corrosion resistance to a wide range of media.
With the high nickel content, Alloy 20 shows good resistance to chloride-induced stress corrosion cracking. In addition the alloy also has good resistance to pitting and crevice corrosion.
In the chemical process market, key applications of Alloy 20 are in sulphuric, phosphoric and nitric acid environments.
The alloy is also commonly used in the food industry for the manufacture of food preservatives (phosphorus oxychloride and phosphorus trichloride).
