Spot Sales of L80-13Cr Oil Tubes and Casing L80-13Cr is a special type of alloy steel with excellent resistance to chemical corrosion. It is mainly used to prevent various forms of corrosion, including oxidation, electrochemical corrosion, and chemical erosion. In many cases, it can withstand a variety of harmful acids and alkalis. It has good wear resistance and hardness, good cold and hot working properties, relatively low cost, and a long service life, making it popular in many industries. Moreover, this material can be used in any environment where excellent corrosion resistance is required, such as chemical plants, power plants, and water treatment stations. Because of its excellent properties, the value of this material is constantly increasing. In summary, L75-ISCR is a very practical corrosion-resistant product. China has been engaged in research and development of 13Cr martensitic stainless steel oil and casing tubes resistant to CO2 and H2S corrosion for several years. Currently, Baosteel and Tianjin Pipe have developed a series of 13Cr and super 13Cr products, which have been applied in major oil fields such as Tarim, Xinjiang, Xi'an Changqing, and Shengli, and have also been exported to the United States, Canada, and other countries. At present, 13Cr martensitic stainless steel has been basically domesticated in China and has partially replaced imported products. Due to the higher alloy element content and manufacturing costs of duplex stainless steel and nickel- based alloys, Chinese steel pipe enterprises can, based on their existing experience and technological accumulation in ordinary 13Cr, continuously improve smelting, pipe rolling, and heat treatment processes through laboratory alloying research to develop high-chromium martensitic stainless steel oil and casing tubes with excellent comprehensive properties. With fast delivery and high quality, we help customers reduce costs and increase efficiency. Our vision is to build an international petroleum pipeline equipment enterprise through integrity and innovation. We welcome leaders and friends from all sectors to visit and cooperate for mutual development. 1.

Oil Casing: What are 13Cr Pipe and Super 13Cr Material? 13Cr Oil Casing 114.3mm Oil casing is an essential equipment in oil and gas extraction. It not only provides structural support for oil wells but also protects the wellbore from corrosion and collapse. Among various materials, 13Cr pipe and Super 13Cr material are highly regarded for their excellent performance. 13Cr pipe is a high-chromium alloy steel with a chromium content of approximately 13%. This material endows the casing with outstanding corrosion resistance, particularly in acidic environments containing carbon dioxide (CO₂) and hydrogen sulfide (H₂S). The addition of chromium enhances the passivation ability of the steel, forming a dense chromium oxide film that effectively blocks the invasion of corrosive media. Additionally, 13Cr pipe possesses high strength and toughness, allowing it to withstand complex downhole conditions.
