The Q690E carbon steel plate sheet price is expected to be stable and tend to fall

Q690E carbon steel plate sheet Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.

BBN company has steel plates production workshops and warehouses with a total area of more than 500,000 square meters, and the total inventory of various types of steel exceeds 1 million tons. Relying on world-leading processing equipment and storage facilities, the company has strong steel production and processing capabilities, comprehensive logistics and logistics services, ensuring that it can efficiently complete more than 1 million tons of hot rolled plates processing business each year.

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product Q690E carbon steel plate sheet annual capacity is 200 thousand tons.

High purity of Q690E carbon steel plate sheet, steel for hydropower: the inclusions P, S and H, O, N gas content in steel are strictly controlled.The steel for hydropower has ideal strength reserve: the yield strength and tensile strength level are controlled moderately, and the surplus is usually controlled in a reasonable yield strength ratio of 50-3.3 and 80MPac6. The yield strength ratio is more reasonable by adjusting the composition and improving the technology.
