Alloy 20

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 sulphuric acid. This super alloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulphuric, phosphoric, and nitric acids. It also contains niobium for stabilization against sensitization and resultant inter-granular corrosion. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Although originally designed for use in sulphuric acid related industries, Alloy 20 is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries. In addition, this super alloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.
