1、Designation: A625/A625M 13 (Reapproved 2018)Standard Specification forTin Mill Products, Black Plate, Single-Reduced1This standard is issued under the fixed designation A625/A625M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, th
2、e year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This specification cov
3、ers single-reduced black plateproduced from low carbon, cold-reduced steel, furnished incoils and cut sizes, for use in the manufacture of containers,closures, signs, toys and other products, as well as for platingapplications.1.2 It may be supplied dry or oiled and with or withoutsurface treatment.
4、 This product is normally supplied with atrimmed edge.1.3 This specification is applicable to orders in eitherinch-pound units (as A625), which is supplied in thicknessesfrom 135-lb base weight (0.0149 in.) and lighter, or SI units (asA625M), which is supplied in thicknesses from 0.378 mm andlighter
5、.1.4 The values stated in either inch-pound or SI units are tobe regarded as standard. Within the text, the SI units are shownin brackets. The values stated in each system are not exactequivalents; therefore, each system must be used indepen-dently of the other. Combining values from the two systems
6、may result in nonconformance with this specification.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued

19、ity control procedures arerequired by the purchaser to obtain optimum utilization of the material.Cut sizes are line-inspected visually and mechanically during production.Sheets having surface imperfections that will not interfere with theirutilizations are included.NOTE 4Single-reduced black plate
20、is highly susceptible to rusting andmust be properly handled during transit and storage.NOTE 5In inch-pound units single-reduced black plate is supplied onan area basis expressed in base boxes. In coils, the number of base boxesis computed from the measured length and the specified width. In cutleng
21、ths, the number of base boxes is computed from the specified lengthand width dimensions and sheet count. For calculating mass, the densityof steel for tin mill products is 0.2836 lbf/in.3. In SI units single-reducedblack plate is supplied on an area basis computed in SITAs. In coils, thenumber of SI
22、TAs is computed from the specified length and the specifiedwidth. In cut lengths, the number of SITAs is computed from the specifiedlength and width dimensions and sheet count. For calculating mass, thedensity of steel for tin mill tests is 7850 kg/m2.4. Surface Appearance and Finish4.1 Surface Appe

24、ecified for special applications.4.1.1.3 7CA smooth finish with grit lines. The surfaceroughness will range from 10 to 25 in. Ra 0.254 to 0.635 mRa. This is the standard finish for tin mill products.4.1.2 Blasted and/or Otherwise Textured Roll Finishes:4.1.2.1 5AA shot-blasted finish (SBF) intended
25、for litho-graphing.4.1.2.2 5CA shot-blasted finish (SBF) for general appli-cations. The surface roughness will range from 30 to 60 in. Ra0.760 to 1.52 m Ra.5. Oiling5.1 Black plate is furnished oiled or dry. Unless indicated bythe purchaser, single-reduced black plate will be supplied dry.Any requir
26、ed oiling treatment will be negotiated between thepurchaser and the supplier.6.
