Low carbon steel plate use a large number of materials, divided into ordinary low carbon steel plate and special steel plate, including low alloy high strength steel and corrosion and heat resistant laminated steel plate. Ordinary low carbon steel plate is divided into cold rolled and hot rolled two, cold rolled steel surface quality is good, used for manufacturing body and so on. Hot rolled plates are used to make car frames and the like.
The type of steel plate is usually divided into three kinds according to its thickness: thick plate (above 6mm), medium thick plate (3-6mm) and thin plate (below 3mm). In terms of plate making process, low carbon steel plate can be divided into cold rolled and hot rolled two kinds. Only hot rolling can produce about 1.2mm of low carbon steel plate and 2mm of stainless steel plate, and thinner plate is made by cold rolling and annealing and tempering rolling.
