Other common names: Carpenter 20, 20Cb-3®, Incoloy® alloy 20
Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. Alloy 20 is a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. In addition, this superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.
What are the characteristics of Alloy 20?
• Excellent general corrosion resistance to sulfuric acid
• Excellent resistance to chloride stress corrosion cracking
• Excellent mechanical properties and fabricability
• Minimal carbide precipitation during welding
• Excels in resisting corrosion to hot sulfuric acids
