In the oil and gas extraction industry, tubing and casing are the lifeline of the wellbore. Facing corrosive environments with high carbon dioxide content, material selection is crucial. Super 13Cr martensitic stainless steel, as an economical and efficient corrosion-resistant alloy, differs fundamentally from conventional carbon steel/low-alloy steel pipes (such as K55, N80, L80).Super 13Cr Oil Casing vs. Conventional Oil Casing:1.
