What is the difference between API 5L X65 PSL1 steel plate, carbon steel pipe and seamless steel pipe? Carbon steel pipe, the performance of this kind of steel pipe is controlled by the amount of carbon content. Different carbon content has different properties and uses. Carbon steel pipe can be seamless or seam welded. Seamless steel pipe is a large category of steel pipe, which can include carbon seamless steel pipe, low alloy seamless steel pipe, high pressure boiler pipe, oil cracking pipe and so on.Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, API 5L X65 PSL1 steel plate based on a high starting point and high technology, the company has vigorously developed various steel products API 5L X65 PSL1 steel plate and deep-processed parts, steel structures, precision castings, seamless pipes.If the chromium content in API 5L X65 PSL1 steel plate alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.Composition characteristics of low alloy structural steel, API 5L X65 PSL1 steel plate: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
