Alloy20 characteristics

N08020 is a niobium stabilized low carbon austenitic nickel-iron-chromium alloy containing copper and molybdenum. It has excellent resistance to acid attack, pitting and crevice corrosion as well as chloride-containing acids and chemicals, general corrosion and intergranular corrosion. It also combines excellent corrosion resistance, ease of fabrication and enhanced mechanical properties. Alloy N08020 is also known as Carpenter 20, Incoloy and 20Cb-3.

Advantage

• Excellent resistance to sulfuric acid and phosphoric acid

• Good resistance to intergranular corrosion

• Extremely resistant to stress corrosion cracking caused by chloride ions

• Good resistance to pitting and crevice corrosion

• Good mechanical properties at room temperature and at elevated temperatures up to about 500°C (930°F)

Product application areas of Alloy20

Alloy 20 is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy. It has a wide range of applications such as chemical, food, medicine, power production and plastics industries.
