The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, a573 grade 70 high strength carbon steel. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, a573 grade 70 high strength carbon steel Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach a573 grade 70 high strength carbon steel 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual a573 grade 70 high strength carbon steel production capacity: 3.5 million tons."
In January 2019, one of our Vietnam customer purchased 395.62 tonsQ345B steel platea573 grade 70 high strength carbon steel for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 a573 grade 70 high strength carbon steel and priming gray oxide primer, and arrange shipment in time.
