A709Gr50 steel is a high-strength low-alloy stee. It is widely used in engineering structures, such as building steel structures, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for those requiring good weldability and toughness Construction and construction machinery parts. BBNsteel’s engineers suggest customer choose low temperature impacting test for steel A709 grade 50 at zero centigree, because these steel plates A709Gr50 normally used in this temperature.
Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of A283 Gr C mild steel coil capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the A283 Gr C mild steel coil overall strength, competitiveness and anti risk ability of the company.
In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of A283 Gr C mild steel coil high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's A283 Gr C mild steel coil technical equipment.
Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the A283 Gr C mild steel coil, stainless steel from corrosion.
Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
