ISO 3574:2012 pdf download.Cold-reduced carbon steel sheet of commercial and drawing qualities.
ISO 3574 applies to cold-reduced carbon steel sheet of commercial and drawing qualities. It is suitable for applications where the surface is of prime importance.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the reference document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
cold-reduced steel sheet
product obtained from hot-rolled descaled steel sheet by cold reducing to the required sheet thickness followed by annealing to recrystallize the grain structure
3.2
skin pass
light cold-rolling of hot-rolled steel sheet or hot-rolled desca led steel
Note 1 to entry: The purpose of the skin pass is to produce a higher degree of surface smoothness and thereby improve the surface appearance. The skin pass also temporarily minimizes the occurrence of a surface condition known as stretcher strain (Luder’s Lines) or fluting during the fabrication of finished parts. The skin pass also controls and improves flatness. Some increase in hardness and loss of ductility will result from skin passing.
3.3
camber
greatest deviation of a side edge from a straight line, the measurement being taken on the concave side with a straightedge
3.4
out-of-square
greatest deviation of an end edge from a straight line at right angles to a side and touching one corner, the measurement being taken as described in ISO 16162, or measurable as one-half the difference between the diagonals of the cut-length sheet
3.5
stabilized interstitial free steel
extra-low-carbon steel in which all interstitial elements are combined with titanium and/or equivalent elements
4 Dimensions
4.1 Cold-reduced carbon steel sheet is produced in thicknesses of 0,36 mm and thicker (commonly produced up to 4 mm) and in widths of 600 mm and over, in coils and cut lengths.
4.2 Cold-reduced sheet less than 600 mm wide can be slit from wide sheet and will be considered as sheet.
5 Conditions of manufacture
5.1 Chemical composition
The chemical composition (heat analysis) shall not exceed the values given in Tables 1 and 2. On request, a report of the heat analysis shall be made to the purchaser.
Each of the elements listed in Table 2 shall be included in the report of the heat analysis. When the amount of copper, nickel, chromium or molybdenum present is less that 0,02 %, the analysis result may be reported as “< 0,02 %“.ISO 3574 pdf download.
