Welcome to BBN High Strength Steels Factory
Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the S690QL data sheet hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the S690QL data sheet steel industry.
BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the S690QL data sheet metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between S690QL data sheet strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
Chemical elements of 35CrMnSi steel: C: 0.32-0.39, Si: 1.10-1.40, Mn: 0.80-1.10, Cr: 1.10-1.40. The mechanical properties of 35CrMnSi steel: tensile strength 1620 MPa; yield strength 1280 MPa; elongation after fracture: 9%; reduction of area: 40; impact energy: 31J. S690QL data sheet, 35CrMnSi steel is used to manufacture medium speed, heavy load, high strength parts and high strength components, such as aircraft landing gear and high pressure blower blades. 35CrMnSi can partly replace the corresponding CrNi alloy steel in manufacturing small and medium section parts.
Based on the principle of “sincerity and win-win cooperation”, our company keeps forging ahead. In the fierce market competition, we have won the trust and rapid development of our customers with good cooperation and sincere service spirit. With pioneering spirit, the pursuit of excellence, continuous learning, and never satisfied content, we will create a win-win situation with our customers to create a better future.
