The difference between cold rolled steel plate and hot rolled steel plate
Cold rolling is made of hot-rolled coils as raw materials, which are rolled at room temperature below the recrystallization temperature. The thickness of the cold-rolled sheet is generally between 0.1-8.0mm, and the thickness of the cold-rolled sheet produced by most factories is below 4.5mm. The thickness and width of the cold-rolled sheet are determined according to the equipment capacity and market demand of each factory.
Hot rolling uses slabs (mainly continuous casting slabs) as raw materials, and after heating, strips are made by rough rolling mills and finishing mills. To put it simply, after a piece of steel billet is heated (that is, the red hot steel block on TV), it is rolled several times, then trimmed and corrected into a steel plate. This is called hot rolling.
Cold rolling: using hot-rolled steel coil as raw material, after pickling to remove oxide scale, cold rolling is carried out, and the finished product is hard-rolled coil. The plastic index decreases, so the stamping performance will deteriorate, and it can only be used for parts with simple deformation.

The difference between quality weather resistant steel plate and ordinary steel plate
The quality weather resistant steel plate is corroded in natural climates, and a dense oxide layer is formed on the surface of the steel, which prevents the oxygen and water in the atmosphere from penetrating into the matrix and plays a role in oxidation; while ordinary steel After rusting, not only the protection of the oxide layer will not appear, but the rust will be more serious.
