Fatigue properties of EN 10025 S620QL high strength steel

The company has allocated special environmental protection facilities for all EN 10025 S620QL high strength steel 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, EN 10025 S620QL high strength steel steel mill scale, environmental protection dust has reached 100%.

"Efficiency is benefit, time is money", the company is equipped with a high standard logistics team. After the products pass the factory inspection, they will coordinate the shipment as soon as possible according to customer requirements and schedules to hand over the booked steel materials to customers at the first time, to ensure no delay of customer's project progress, to strive for more project preparation time for customers.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, EN 10025 S620QL high strength steel Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach EN 10025 S620QL high strength steel 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual EN 10025 S620QL high strength steel production capacity: 3.5 million tons."

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the EN 10025 S620QL high strength steel project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.

Q355B steel and EN 10025 S620QL high strength steel steel
Both Q345B and Q355B are low alloy steels. The difference is that the yield strength of Q345B low alloy steel and Q345B low alloy steel is different. In Q345B low-alloy steel, q represents the yield strength of this material, and the latter 345 represents the yield value of this material is around 345mpa. Q in Q355B low-alloy steel also represents the yield strength of this material, and the latter 355 indicates that the yield value of this material is around 355mpa.

We specialize in the production and sale of steel products. We have many customers from all over the world. Our products EN 10025 S620QL high strength steel have strict quality inspection departments, so we have absolute quality and technical advantages. Good promotion system, with advanced business philosophy, create development space, enhance the value of employees, improve the quality of life as the mission.
