Kencotube is a known trader and stockist and Alloy 20 Pipes and Tubes, which can successfully be hot formed by using forces similar to those required by austenitic stainless steels. Alloy 20 Tubes is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless. Alloy 20 Seamless Pipes is often used for Bubble caps, Petrochemical process equipment, Food and dye production and more. Alloy 20 Welded Pipes is an excellent choice for a wide variety of industries and applications, which is also used in Process piping, Mixing tanks, Chemical and petroleum process equipment. Alloy 20 EFW Pipes has an excellent cold formability, wheredrawing, pressing, bending, and other-related forming functions that happen in the manufacturing process of made-up items are voluntarily performed.
Alloy 20 ERW Pipes also has good mechanical properties at both ambient and elevated temperatures, which excels in resisting corrosion to hot sulphuric acids. UNS N08020 Pipes is composed of carbon, chromium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, and sulphur. UNS N08020 Tubes has superior resistance to stress-corrosioncracking in boiling 20 to 40 percent of sulphuric acid. Alloy 20 Seamless Tubes resists chloride ion and pitting corrosion and its content of copper protects the same from sulphuric acid. Alloy 20 Wedled Tubes can normally be press brake bent over a radius twice the materials thickness. Alloy 20 EFW Tubes has excellent resistance to hot sulphuric acid and chloride stress corrosion cracking resistance.
