The difference between cold rolled steel and hot rolled steel lies not in the smelting process, but in the rolling temperature, or the end temperature of rolling. If the final rolling temperature is lower than the recrystallization temperature of steel, i

P355gh is a European standard container plate, which implements en10028 standard. P355gh is close to the national standard Q345R. P355gh + n means that the steel plate is delivered in normalized state. As a pressure vessel, the steel plate can be used to

There are three basic types of surface rolling for sheet and strip, which are represented by sheet and strip production processes.
No.1: after hot rolling, annealing, pickling and descaling. The surface of the treated steel sheet is a dull surface and a b

There is a certain difference in the mechanical energy of steel plate (especially thick plate) in three directions, which is due to the metal deformation and the formation of layered microstructure in the rolling process. Generally, the performance along

In hot-rolled steel plate, the mechanical properties of steel plate in rolling direction and transverse direction are different, which is mainly caused by the difference between transverse and longitudinal deformation of steel plate. In the rolling proces
