The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. JIS carbon steel SM490YA CS plate, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.
