6mm thick P355NH properties stock resources

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between P355Nh-steel-plate-for-boiler-and-vessel.html target=_blank class=infotextkey>P355NH properties, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of P355Nh-steel-plate-for-boiler-and-vessel.html target=_blank class=infotextkey>P355NH properties, 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.
