S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. A514 Gr A alloy steel plate, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
What are the characteristics of medium and thick plate, A514 Gr A alloy steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, A514 Gr A alloy steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of A514 Gr A alloy steel plate circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and A514 Gr A alloy steel plate management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
In October, the demand for finished products improved significantly, breaking through the high of 4.4 million tons per week, and the price of black products went up overall. Among them, coke performed particularly well under the stimulus of downstream shortages and high molten iron output. It wasn't until early November that coke futures prices fell from a high level due to high disk premiums. After six rounds of increases, the spot price also began to weaken. Downstream steel mills were more resistant to the seventh round of increases.
