Product brief introduction
Alloy 20( UNS N08020) 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.
The following sections will discuss in detail about nickel alloy
20.
