Compared with cold-rolled steel plate manufacturing process is simpler, the cost is also cheaper, but foreign experience believes that hot rolling method is only suitable for the manufacture of steel plate thick more than 1.6 mm, for thinner steel plate is not economical, hot-rolled steel plate surface quality and dimensional accuracy are not as good as cold-rolled steel plate, hot rolled steel plate on the car, in addition to frame stringers, beams and various brackets, but also stamping wheel rims, wheel discs, etc. that require a certain strength, as well as shell covers with little force and surface requirements are not too high. The former is a thick 3-5 mm steel plate, the latter is used in medium plates and thin plates, and the use of hot-rolled plates on automobiles is mostly thick plates. In the standard for hot SLSN plates for automobiles formulated by the Japan Automobile Association, SAPH class is used as a vehicle beam and wheel, and SPH class is a hot-rolled mild steel plate for manufacturing unstressed shells.
