Our A709 grade 50W high strength steel pipeline steel has once again helped the construction of the China-Russia East Line Natural Gas Pipeline. During 2017 - 2018, the company successively supplied more than 10,000 tons of high-grade pipeline steel materials for the northern section of the Sino-Russian Eastern Gas Pipeline project, helping the northern section of the A709 grade 50W high strength steel project to be successfully completed. Now we reload the task and will provide API 5L X80 high-grade pipeline steel for the middle section of the China-Russia Eastern Gas Pipeline project.
The chromium plays an important role in A709 grade 50W high strength steel, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
