Our company was founded in 2000, which initially committed to providing high-quality steel sa573gr.70 steel equivalent products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export sa573gr.70 steel equivalent steel to the international market, opening up the international steel market.
We have transportation department and shipping department to coordinate logistics and delivery. Seamless connection between inland transportation and sea transportation ensures smooth delivery, saves transportation time and delivers goods in the first time. During the sea transportation, we will update the freight progress for customers on a regular basis, so as to facilitate the tracking of customers and make preparations for receiving goods leisurely and timely.
EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as sa573gr.70 steel equivalent high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging cold
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous sa573gr.70 steel equivalent pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, sa573gr.70 steel equivalent. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
