Corrosion Behavior of Super 13%Cr Martensitic Stainless Steel Under Ultra-deep,Ultra-high Pressure and High Temperature Oil and Gas Well Environment

By simulating ultra-deep,ultra-high pressure and high temperature oil and gas corrosion environment,the performance of super 13%Cr martensite stainless tubular goods against uniform corrosion,pitting and galvanic corrosion was studied.The results indicate that the uniform corrosion rate of super 13%Cr martensite stainless steel increases as the Cl-concentration increasing in gas phase,and changes little in the liquid phase.The uniform corrosion...
