Alloy20 Characteristics
Alloy N08020 is a nickel-iron-chromium austenitic alloy with excellent resistance to acid attack, pitting and crevice corrosion as well as chloride-containing acids and chemicals, general corrosion and intergranular corrosion. The alloy combines excellent corrosion resistance, ease of fabrication and enhanced mechanical properties.
Alloy N08020 is also known as Carpenter 20, Incoloy and 20Cb-3.
N08020 is a niobium stabilized low carbon austenitic nickel-iron-chromium alloy containing copper and molybdenum.
• Excellent resistance to sulfuric acid and phosphoric acid Corrosion
• 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)
Specific gravity: 8.08;
N08020 corrosion resistance:
N08020 exhibits excellent corrosion resistance to aqueous solutions of sulfuric acid, phosphoric acid and organic acids and their salts. It also has good nitric acid corrosion resistance. By adjusting the chemical composition, it exhibits excellent resistance to various types of corrosion such as intergranular corrosion and stress corrosion. Molybdenum is also included to ensure resistance to pitting and crevice corrosion. To maximize corrosion resistance, the material must be kept metallurgically correct and clean.
N08020 contains copper and molybdenum, which enhance the material’s resistance to harsh environments and resistance to pitting and crevice corrosion. Niobium is used to stabilize the material and minimize carbide precipitation during welding. This allows welding consumables to be used in corrosive environments without post-weld heat treatment of them. Nickel increases resistance to chloride corrosion cracking.
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 will use it. Resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.
