The development A709 Gr 50W bridge steel plate of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with A709 Gr 50W bridge steel plate high-quality and efficient services, work together for win-win, and create a better tomorrow!
Shipbuilding steel is a kind of steel plate used by shipyards, shipbuilding companies and dockyards to manufacture hulls of cargo and passenger ships, boats, offshore drilling platforms, gateways and other structures and vessels. The company also supply AB AH36 plates and steel sheets A709 Gr 50W bridge steel plate in coils or cut to length, steel profiles (steel bulb flats, rounds and squares), and round and profiled tubes made from shipbuilding steel grades. Shipbuilding steel is produced under the control of certifying societies, sea and river registers.
Our stainless steel mainly is stainless steel plate/Coil. We keep 2600 tons stainless steel plate and coil A709 Gr 50W bridge steel plate in stock. And we refresh the our new stock every month. All the stock products from reputable mills like like TISCO, ZPSS, IISCO, LISCO, Bao steel and so on. We put all our products in Shanghai and Tianjin warehouse, which is near the loading port.
Corrosion resistance mechanism of A709 Gr 50W bridge steel plate, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
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, A709 Gr 50W bridge steel plate. 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.
