Alloy 20 Tubing , also known as Carpenter 20 Tubing , is a nickel -iron chromium Austeen alloy. Add copper to alloy 20 seamless tubes to protect the metal grade from sulfuric acid erosion. The alloy contains chloride and sulfuric acid, which is resistant to corrosion in chemicals with phosphate and nitrate. In addition, it also has excellent point of resistance and gaps. Therefore, ASTM B729 UNS N08020 Pipe is used in key industrial fields (such as chemistry, petrochemical, power generation).
