[0002] Steel plate is cast with molten steel, and is pressed into flat plate after cooling. Usually, steel plate is flat and rectangular, which can be directly rolled or cut from wide steel strip. Steel plate is divided into thin steel plate (less than 4mm, the thinnest 0.2mm), thick steel plate (4-60mm) and extra-thick steel plate (60-115mm) according to thickness. Steel plate is divided into hot-rolled steel plate and cold-rolled steel plate according to rolling. Steel plate has bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, etc.
