Product Description:

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.

Q:What material is steel plate against drilling?
All high nickel, high tungsten, or both titanium (tungsten carbide and titanium carbide), cobalt, molybdenum, niobium and other elements of the steel can be drilled.
Q:What are the functions and classifications of galvanized sheet?
Galvanized sheet mainly used in industry: a large number of galvanized sheet, used in automobile manufacturing, refrigeration, construction, ventilation and heating facilities and furniture manufacturing and other fields. Galvanized steel anticorrosion method becomes important, not only because the zinc can form a protective layer on the surface of iron and steel, but also because zinc has the effect of cathodic protection, when the breakage of zinc coating, it can still prevent iron base metal corrosion by cathodic protection.
Q:What's the difference between single rolling steel sheet and continuous rolling steel plate?
Single rolled steel plate usually refers to medium plate, in the process of rolling and finishing, the plate has been flat, usually thicker (6mm or more), the width of the fastest up to 4800mm.
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
During piling, sometimes large blocks of stone or other unknown obstacles are encountered, which results in inadequate penetration of steel sheet piles and the use of corner piles or arc piles to bypass obstructions.
Q:What's the difference between the three kinds of pickling plate, cold rolled plate and hot rolled plate?
Cold rolled plate: that is, the cold rolled base plate (that is, hot rolled plate) rolled in the normal temperature condition. Because of the great cold rolling stress, it usually goes through the annealing process
Q:What is the aging property of steel plates?
Timeliness refers to the change in performance with time.
Q:How can the white steel plate be bright and cleaned?
White steel plate has higher plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an alloy steel which is not easily rusted, but it is not absolutely rusty.
Q:Can the steel surface be made of epoxy resin flooring?
Because of the problem of surface adhesion, special coatings should be used, such as zinc rich primers, polyurea coatings, etc..
Q:What's the difference between steel plate 20 and Q235 steel plate?
20 is a high-quality carbon structural steel, Q235 is carbon structural steel, and steel 20 is higher than Q235.According to the application of the situation, the two kinds of steel generally in the load is not large, the requirements are not high can be exchanged
Q:16 what is the hardness of manganese steel plates?
16 hardness of manganese steel plate is 45 -50HRC.
