BBN A515 Gr 70 pressure vessel steel sheet with good performance

Most common A515 Gr 70 pressure vessel steel sheet steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled A515 Gr 70 pressure vessel steel sheet steel plates.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A515 Gr 70 pressure vessel steel sheet production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. A515 Gr 70 pressure vessel steel sheet, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.

Steel transportation because of the special material of A515 Gr 70 pressure vessel steel sheet steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
