ASTM B729 UNS N08020 Nickel Alloy Seamless Acid-resistant Pipe
TONG CHUANG Group as one of the leading suppliers in China to supply nickel alloy and tubes，etc.，we have many experiences in exporting.
Developed to exhibit good corrosion resistance properties， the UNS N08020 Alloy is an alloy which has exceptional resistance to sulfuric acid. The content of copper added to the Alloy 20 is what protects this metal grade against sulfuric acid. Hence， the Carpenter 20 Pipe UNS N08020 Pipe finds use in key industrial sectors such as chemical， petrochemical， power generation， as well as the plastic industries
ASTM B729 This specification covers UNS N08020， UNS N08026， and UNS N08024 seamless， cold-worked or hot- finished pipe and tube intended for general corrosive service.
