The carbon content of hot rolled steel sheet is slightly higher than that of cold rolled steel sheet. The density is the same when the composition is not very different. However, if the composition of stainless steel varies greatly, the density of cold-rolled and hot-rolled stainless steel sheets is about 7.9g/cm3. Specific also depends on the composition, hot-rolled steel plate is only better ductility, steel is also subject to pressure.Hot rolled steel plate is divided into structural steel, low carbon steel, welded cylinder steel, and then according to various steel to find the steel you need, in order to find the density and composition of specific steel.
