Development of S960Q steel pipe in China

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our S960Q steel pipe steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge S960Q steel pipe steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

BBN company is one of the most important manufacturers of S960Q steel pipe medium and heavy steel plates for shipbuilding in China. The general strength shipbuilding steel Grades A, B, D, E and higher-strength grade AH32, AH36, DH32, DH36, EH32, EH36 hull structural steel plates produced by heavy steel (specifications: 6-32mm) have been obtained by nine classification society approval certificates Like ABS, CCS, LR, DNV, GL, RINA, and KR.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. S960Q steel pipe, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S960Q steel pipe carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S960Q steel pipe alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. S960Q steel pipe, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, S960Q steel pipe sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
