S690QL equivalent indian standard 4mm mild steel sheet

Our company supply the cold rolled steel coil for customers, and the cold rolled steel coil we produce the standard of JIS, EN, DIN. The available grades include the JIS G 3141 SPCC, SPCD, SPCE, S690QL equivalent indian standard and so on. The EN 10111 standard include DD11, DD12, DD13, DD14. The EN 10130 standard include DC01, DC03, DC04 etc. The standard of DIN 1623 available grades have ST12, US113, RRST13 and ST14.

The company adopts the S690QL equivalent indian standard international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S690QL equivalent indian standard management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S690QL equivalent indian standard are higher than that of annealed S690QL equivalent indian standard, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL equivalent indian standard is simple, the cost is low, the productivity is high, and it is widely used in actual production.

After extrusion, the S690QL equivalent indian standard tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
