After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, ASTM A572 ms steel coil 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 ASTM A572 ms steel coil steel and 542,000 tons of steel.
BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.
Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. ASTM A572 ms steel coil, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.
The structure of NM360 wear-resistant steel plate: The test found that whether it is a grinding ball, a forehead plate, or a hammer, after casting, it can get a structure based on wear-resistant steel after taking out air cooling at a temperature greater than 850℃. Transmission electron microscopy analysis of the metal thin film shows that there is a high density of dislocations in this type of wear-resistant slats, and there is an austenite film between the slats. Due to the high carbon content in this austenitic film, it has high stability. It is the shape of the ASTM A572 ms steel coil, wear-resistant plate that makes the steel have a good combination of strength and toughness.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s ASTM A572 ms steel coil domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
