what we do besides C22 steel pipe?

Alloy 20 Pipe ASTM B729 N08020 DIN 17751 2.4660 is a high-corrosion resistant alloy, which shows very good resistance to phosphoric acid, nitric acid, sulfuric acid in chloric media. DIN 17751 2.4660 Alloy 20 is chiefly used in the chemical industry, apparatus engineering and heat exchanger.

Alloy 20 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.

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.

ASTM B729 Alloy 20 N08020 Alloy Tubing Tubes Pipe have a good resistance properties to pitting and crevice corrosion and good resistance to intercrystalline corrosion, stress corrosion.
