DIN S235JR ST37 Carbon Steel Plates

DIN S235JR ST37 Carbon Steel Plates,Carbon steel plate can be divided into cold rolling plate and hot rolling palte in terms of plate making process.Hot rolled steel sheets are easier to manufacture and cheaper than cold rolled steel sheets, but foreign experience believes that hot-rolled steel plate are only suitable for manufacturing steel plate with a thickness of more than 1.6 mm, and are uneconomical for thinner steel plates. The surface quality and dimensional accuracy are not as good as cold rolled steel plates, hot rolled steel plates on automobiles, in addition to frame longitudinal beams, beams and various brackets, but also punching wheel rims, wheel discs, etc. The former is a steel plate with a thickness of 3-5 mm, and the latter is used for both medium and thin plates. The amount of hot rolled plates used in automobiles is mostly thick plates.
