2、 revision, the 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.1. Scope*1.1 This specification covers double-reduced black plate, produced from low-carbon cold-reduced st
3、eel, furnished in coils andcut sizes, for use predominantly in the manufacture of containers. The product may be specified “as rolled,” without the removalof the rolling solution, and with no additional surface or oiling treatment. It may also be specified “cleaned” with the rollingsolution removed,
4、 with or without surface treatment and oiling. This product is normally supplied with trimmed edges.1.2 This specification is applicable to orders in either inch-pound units (as A650) which is supplied in thicknesses 0.0050 in.to 0.0113 in. or SI units as A650M which is supplied in thicknesses from
5、0.127 to 0.287 mm.1.3 The values stated in either inch-pound or SI units are to be regarded as standard. Within the text, the SI units are shownin brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of theother. Combining values fro

19、 same opportunity for inspection, grading, and sorting as does the production of cut sizes.Accordingly, appropriate processing and quality control procedures are required by the purchaser to obtain optimum utilization of the material. Cut sizesare line-inspected visually and mechanically during prod
20、uction. Sheets having surface imperfections that will not interfere with their utilization areincluded.NOTE 4Double-reduced black plate is highly susceptible to rusting and must be properly handled during transit and storage.NOTE 5In inch-pound units, double-reduced black plate is supplied on an are
21、a basis expressed in base boxes. In coils, the number of base boxes iscomputed from the measured length and the specified width. The theoretical weight of a coil is computed by multiplying the number of base boxes ina coil by the specified base weight. In cut lengths, the number of base boxes is com
22、puted from the specified length and width dimensions and sheet count.The theoretical weight of a bundle is computed by multiplying the number of base boxes in the bundle by the specified base weight.In SI units, double-reduced black plate is supplied on an area basis expressed in SITAS.SITAs. In coi
23、ls, the number of SITASSITAs is computed fromthe measured length and the specified width. In cut sizes, the number of SITASSITAs is computed from the specified length and width dimensions andsheet count. For calculating mass, the density of steel for tin mill products is 7850 kg/m3 (see Specificatio
24、n A623M).4. Rolling Direction4.1 Double-reduced black plate is relatively brittle and has very distinct directional properties. The rolling direction must bespecified on cut lengths and will be indicated by underlining the slit (rolling width) dimension. To minimize the flange-crackinghazard when th
25、e product is used for can bodies, the rolling direction must be around the circumference of the can.5. Surface Finish5.1 Base Metal FinishDouble-reduced black plate is produced with a ground roll finish.5.1.1 7CA smooth finish with grit lines. The surface roughness will range from 6 to 25 in. Ra 0.1
26、52 to 0.635 m Ra. Thisis the standard finish for tin mill products.6.
