Alloy 20 (UNS N08020, W. Nr 2.4660) also known as Carpenter 20 and Incoloy 20, is an iron-base, austenitic nickel-iron-chromium alloy with excellent corrosion resistance to sulfuric acid and other aggressive environments.
Alloy 20 is a nickel-iron-chromium alloy with addition of copper and molybdenum providing resistance to hostile environments, pitting, and crevice corrosion. Carpenter 20 appears to fall between both the stainless and nickel categories as it contains characteristics of both. Incoloy 20 was designed for maximum resistance to acid attack and demonstrates superior resistance to stress-corrosion cracking in boiling 20% to 40% sulfuric acid, and also has excellent general corrosion resistance to sulfuric acid and to chloride stress corrosion cracking. Nickel Alloy 20 has good mechanical properties at both ambient and elevated temperatures, up to approximately 930°F (500°C) and is readily fabricated by usual industrial processes. Carpenter 20 is commonly used for chemical, pharmaceutical and food processing, tanks, piping, heat exchangers, pumps, and much more.
