The company has allocated special environmental protection facilities for all A514 grade B structural steel material pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, A514 grade B structural steel material steel mill scale, environmental protection dust has reached 100%.
S890 steel is a quenched and tempered high-strength steel plate, the series grades are S890Q, S890QL, S890QL1. S890Q, S890QL, S890QL1 steel,A514 grade B structural steel material plates, where S means structural steel, Q means that the impact temperature of the steel plate is -20°C, and QL means that the impact temperature of the steel plate is -50°C. Then guess what QL1 stands for. QL1 means that the impact temperature of the steel plate is -60°C, and 890 means that the thickness is £50mm.
304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material A514 grade B structural steel material is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.
After adding a small amount of niobium, vanadium and titanium to A514 grade B structural steel material etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
A514 grade B structural steel material, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.
