Duplex Steel Pipes

 

 

Due to the need to overcome the shortcomings of austenitic and ferritic steels, duplex steels have appeared on the market. It was found that a mixture of these two materials resulted in higher strength, reduced weight, good weldability, and improved resistance to stress corrosion cracking.
