High quality Q235 S235 S275 S355 hot carbon steel sheet plate

Steel plate is a kind of material which is used very much, which is divided into ordinary low carbon steel plate and special steel plate, including low alloy high strength steel and corrosion resistant and heat resistant cladding steel plate. Ordinary low carbon steel plate is divided into cold rolled and hot rolled two kinds, cold rolled steel plate surface quality is good, thickness size is accurate, used for manufacturing body and so on. Hot rolled plate is used to make frame and so on.
Types and uses of low carbon steel plate

The types of steel plate are usually divided into thick plate (more than 6mm), medium thick plate (3-6mm) and thin plate (below 3mm) according to its thickness. Low carbon steel plate can be divided into cold rolling and hot rolling. Hot rolling alone can produce low carbon steel plates of about 1.2mm and stainless steel plates of about 2mm. Thinner plates are made by cold rolling and annealing and tempered rolling.

Cold rolled steel sheet

Cold rolled steel plate used in parts forming requires large plastic deformation degree of material, surface should not have wrinkle, crack and other parts. Different grades of steel plates are used for different parts. For example, Japanese automobile steel plate standards are divided into three categories, the first category (SPCC) is ordinary cold rolled steel plate, usually rolled by boiling steel, the second category (SPCD) is calenderized steel plate, the third category (SPCE or SPCEN) is deep drawn cold rolled steel plate.

In the past, due to the large component segregation of boiling steel, unstable performance, aging sensitive, limited to unimportant stamping parts. The cost of aluminum-killed steel without timeliness is 10-20% higher than that of ordinary boiling steel. In the past, smooth cold rolling was used to suppress the aging of boiling steel plate, but in fact it only delayed the aging. Countries are researching new and improved methods. Developed by the United States of America loose coil annealing steel plate (O.C.A) is the boiling steel plate in the atmosphere containing water steam and hydrogen for special annealing, because of this atmosphere annealing can remove the solid solution in the steel and carbide in the combined carbon, inhibit the aging sensitivity, and further soften the steel plate. At the same time, due to the growth of recrystallized grains, the composition of {111} aggregate crystals parallel to the surface of the steel plate increases. According to the study of Armco iron and steel companies in the United States, which is associated with the plastic deformation anisotropy of improving steel plate, the stamping formability of steel plates by 84, in recent years, on the basis of loose coil annealing steel plate and the development of the joint plate (U.A.D) annealing method, the rolls of steel plate welded into a roll, and in particular in the annealing furnace on decarburization process, It has the advantage of less cost than loose coil annealing and has been widely used in cold rolled steel for stretching.

Hot rolled steel plate

Than cold rolled steel manufacturing process is simple, the cost is cheap, but the experience of abroad think hot rolling method is only applicable to manufacture more than 1.6 mm thick steel plate, the more thin plates is not economic, hot rolled steel plate surface quality and dimension precision are worse than cold rolled steel, hot rolled steel plate, car in addition to the frame longitudinal beam, beam and a variety of stents, Also stamping requirements of a certain strength of the wheel rim, wheel, etc., as well as the force is not large, the surface is not too high shell cover plate, etc. The former is 3-5 mm thick steel plate, while the latter is used for medium plate and thin plate. The hot rolled plate used in automobile is mostly thick plate. According to the standard of hot SLSN plate for automobile developed by Japan Automobile Association, SAPH class is used for car beam and wheel, while SPH class is used for hot rolled soft steel plate to make shell without stress.
