EN 2.4660 Alloy 20 Seamless Nickel Alloy Pipe Tube DN8 - DN400 With EN 10204-3.1 Certificate

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).

Features of Alloy 20

• • Excellent basic corrosion resistance to sulfuric acid
• • Excellent protection to chloride stress rust cracking
• • Excellent mechanical qualities and fabricability
• • Minimal carbide precipitation for the duration of welding
• • Excels in resisting corrosion to very hot sulfuric acids
