UNS N08020 | Werkstoff 2.4660 |
Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid. This superalloy has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. It also contains niobium for stabilization against sensitization and resultant intergranular corrosion. Carpenter 20 combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. Although originally designed for use in sulfuric 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 superalloy is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping.
Alloy 020 (UNS N08020, W. Nr 2.4660) is a nickel-iron-chromium alloy which has the addition of copper and molybdenum. With the additions of niobium Alloy 020 is stabilized against sensitization and resultant intergranular corrosion. Alloy 020 has excellent resistance to general corrosion, pitting and crevice corrosion and is commonly used for chemical, pharmaceutical and food processing, tanks, piping, heat exchangers, pumps, Kevlar production and much more.
There has long been a debate on whether Carpenter 20 is a stainless steel or a nickel alloy because the nickel content is right on the border of defining it as one way or the other. So, depending on who you talk to this alloy may be referred to as alloy 20 Stainless Steel or as a nickel alloy. Either way it is still great for corrosion resistance.
