8*2400*10000 S690QL rockwell hardness MS Mild Steel Plates

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S690QL rockwell hardness tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S690QL rockwell hardness steel and 542,000 tons of steel.

BBN is a big team with great centripetal force. The company adheres to the tenet of "creating value for customers, creating benefits for enterprises, creating wealth for employees, and creating prosperity for society". Adhere to the strict management of factories, technology-oriented, adhering to "standard management, adhere to integrity, the pursuit of excellence, pragmatic innovation "Business philosophy, we are committed to creating a full-process, low-cost, high-quality, green and environmentally friendly stainless steel manufacturing enterprise.

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, S690QL rockwell hardness product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.

S500MC steel plate/sheet,EN10149 S500MC steel plate/sheet, under EN standard, we can regard S500MC steel plate/sheet as high yield strength steels for cold-forming steels. S690QL rockwell hardness, EN10149 S500MC is mainly used as high yield strength steels for cold-forming steels. The EN10149 S500MC steel is equivalent to SEW092 QStE500TM, NFA E490D, UNI FeE490TM and ASTM X70XLK steel grades.

The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product S690QL rockwell hardness quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.

Welcome to our company to purchase, our products are exported to all parts of the world every month, the quality is guaranteed, the S690QL rockwell hardness price is very preferential. Therefore, it has won great trust and praise from customers. Every month, it needs to purchase some steel plates, steel pipes and other major products. If you have any need, please contact us in time!
