Our A709 grade 50 structural 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 50 structural 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 effect of alloy elements of A709 grade 50 structural steel, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
Supply Range of Carbon Steel C45 Round Bar Round Bar: diameter 8mm – 3000mm A709 grade 50 structural steel Plate: thickness 10mm – 1500mm x width 200mm – 3000mm C45 Steel Flat Bar: 200mm – 1000mm Square Steel: 20mm-800mm Surface Finish: Black, Rough Machined, Turned or as per given requirements.
