Main advantages and disadvantages of s355j2 carbon steel plate

The metal properties and mechanical properties of s355j2 carbon steel plate low-carbon steel sheets are divided into boiling steel and aluminum-killed steel according to the different deoxidation methods used in the steelmaking process (melting, ingot casting and plate solidification).

The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.

Common specifications for cold-rolled plates: thickness 0.2-4mm, width 600-2000mm, length 1000-6000mm.Commonly used grades: Q19-Q23, Q19F-Q23F, Q29(B)-Q345 A(B); SPCC, SPCD, SPCE, DC01-06.Because rolling at room temperature does not produce iron scale, the cold-rolled sheet has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical and technological properties are better than hot-rolled thin steel sheets s355j2 carbon steel plate. In many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets."

The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, s355j2 carbon steel plate.
