Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A514 Gr P structural steel material based on a high starting point and high technology, the company has vigorously developed various steel products A514 Gr P structural steel material and deep-processed parts, steel structures, precision castings, seamless pipes.
S355J2 is a European standard low alloy high strength structural steel grade, equivalent to Q345D. Because of its good impact toughness and welding performance, S355J2 steel plate is widely used in bridges, ships, power plant equipment, hoisting and transportation machinery, machinery manufacturing and other engineering and welding structures that bear high loads. S355J2 steel plate delivery status: hot rolled delivery, the A514 Gr P structural steel material specific delivery status should be indicated in the contract.
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.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A514 Gr P structural steel material, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
