Din 2.4819, 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, Din 2.4819 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.
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 Din 2.4819 Stainless steel or as a nickel alloy. Either way it is still great for corrosion resistance.

Characteristics:
1. Excellent general corrosion resistance to sulfuric acid
2. Excellent resistance to chloride stress corrosion cracking
3. Excellent mechanical properties and fabricability
4. Minimal carbide precipitation during welding
5. Excels in resisting corrosion to hot sulfuric acids
