Properties and Selection of Typical Corrosion Resistant Alloy OCTG
In order to improve the rationality of selecting corrosion resistant alloy OCTG,three types of typical resistant alloy including super duplex stainless steel,20Cr-32Ni iron-nickel base alloy and Ni-Fe-Cr-Mo-Cu iron-nickel base alloy were introduced from aspects of compo-sition and mechanical properties.The performance of stress corrosion resistance,uniform corrosion resistance,and pitting corrosion were an-alyzed especially.The results show that the three types of materials have good performance such as high strength,Cl-stress corrosion resist-ance,high temperature corrosion resistance,and H2 S stress corrosion resistance.They are suitable for various working conditions and meet the requirements of high-quality,green,and low-carbon development in the oil and gas industry.Furthermore,selection suggestions were given for the three types of alloy,which can provide reference for the design of pipe strings in corrosive environments.
