Stainless Steel-Alloy 20
Alloy 20 Description
Nickel alloy 20 is a low-carbon, niobium-stabilized austenitic nickel/iron/chromium alloy with additions of molybdenum and copper. It exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, nitric acid, chlorides and sulfuric acid. It also has good mechanical properties at both ambient and elevated temperatures.
