Cold rolled sheet steel is a plain carbon structural steel cold rolled platereferred to, also known as cold rolled plate, commonly known as cold plate, is sometimes mistakenly written in cold rolling plate. Cold plate is made of hot rolled strip made of ordinary carbon structural steel, thickness of less than 4mm after further cold rolling steel plate. Because the rolling at room temperature, does not produce the oxide scale, therefore, the surface quality of cold plate, high size precision, coupled with the annealing treatment, themechanical properties and process performance are better than the hot rolled thin steel sheet, in many fields, especially the field of the manufacture ofhousehold appliances, has been gradually replaces the hot rolled thin steel sheet.

Cold rolling sheet uses a very wide, such as automotive manufacturing,electrical appliances, vehicles, aerospace, precision instrument, canned food.

Application of brands: Q195, Q215, Q235, Q275; SPCC (Japanese brands);ST12 (German designation)

The general structure of Japan said method for steel grades (JIS standard)

Common structure steel 1 Japanese steel grades mainly consists of three parts: the first part of said materials, such as: S (Steel) said steel, F (Ferrum)said iron; the second part represents a shape, type, different applications,such as P (Plate) said the board, T (Tube) said tube, K (Kogu said tool; the third part) represent the feature numbers, generally is the minimum tensile strength. Such as: SS400, the first S said steel (Steel), second S said "structure" (Structure), 400 for the lower tensile strength of 400MPa, the integral representation for the general structure of the tensile strength of 400MPa steel.

2.SPHC - the first S for steel Steel is an abbreviation for Plate, P inabbreviation, H is a hot Heat acronym, abbreviation for C businessCommercial, the integral representation of hot rolled steel plates and strips for general use.

3.SPHD says hot steel sheets and strip for stamping.

4.SPHE hot rolled steel plates and strips expressed deep drawing.

5.SPCC cold rolled carbon steel sheet and strip, said the general, equivalent to China Q195~Q215A grade, ST12. grade Germany abbreviation Airbenderthird letters of C cold Cold. To ensure the mechanical properties, in the end add T brands such as SPCCT.

6.SPCD cold rolled carbon steel sheet and strip - said by stamping, equivalent to China 08AL (13237) quality carbon structural steel, equivalent to theGerman brand ST13.

7.SPCE cold rolled carbon steel sheet and strip expressed deep drawing, the equivalent of the Chinese 08AL (5213) deep drawing steel, equivalent to theGerman brand ST14. Aging treatment, in the end add N brands, such as SPCEN.

Cold rolled steel sheet and strip for Quenched and tempered Code: annealingstate A standard conditioning for S, 1/8 for 8,1/4 is 4,1/2 hard hard hard hard2, 1.

Surface processing code: Matt finishing D, bright finish rolling for B. As SPCC-SD said, for general use standard tempered cold-rolled carbon sheet mattefinish rolling. As SPCCT-SB said standard conditioning, light processing,requests to guarantee cold-rolled carbon sheet mechanical properties.
