1. What is Alloy 20?

Alloy 20(UNS N08020), or Carpenter 20, is an austenitic nickel-based alloy developed for superior corrosion resistance in sulfuric acid environments, as well as resistance to pitting and crevice corrosion in chloride-rich conditions. With molybdenum (2.0-3.0%) and copper (3.0-4.0%), Alloy 20 material excels in chemical processing equipment, making Alloy 20 plate ideal for reactors and storage tanks. It offers better sulfuric acid resistance than Alloy 825 due to higher copper content.

How Does Alloy 20 Compare to Alloy 28?

Alloy 20(UNS N08020) is optimized for sulfuric acid resistance with higher copper, while Alloy 28 (UNS N08028) excels in phosphoric acid due to higher molybdenum. Alloy 20 plate is preferred for sulfuric acid chemical processing.
