1、Designation: A 650/A 650M 03Standard Specification forTin Mill Products, Black Plate, Double Reduced1This standard is issued under the fixed designation A 650/A 650M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last
2、 revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) 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 steel, furnished incoils and
3、cut sizes, for use predominantly in the manufacture ofcontainers. The product may be specified “as rolled,” withoutthe removal of the rolling solution, and with no additionalsurface or oiling treatment. It may also be specified “cleaned”with the rolling solution removed, with or without surfacetreat
4、ment and oiling. This product is normally supplied withtrimmed edges.1.2 This specification is applicable to orders in eitherinch-pound units (as A 650) which is supplied in thicknesses0.0050 in. to 0.0113 in. or SI units as A 650M which issupplied in thicknesses from 0.127 to 0.287 mm.1.3 The value
5、s 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 systemsmay result in

19、s suppliedon an area basis expressed in base boxes. In coils, the number of baseboxes is computed from the measured length and the specified width. Thetheoretical weight of a coil is computed by multiplying the number of baseboxes in a coil by the specified base weight. In cut lengths, the number of
20、base boxes is computed from the specified length and width dimensionsand sheet count. The theoretical weight of a bundle is computed bymultiplying the number of base boxes in the bundle by the specified baseweight.In SI units, double-reduced black plate is supplied on an area basisexpressed in SITAS
21、. In coils, the number of SITAS is computed from themeasured length and the specified width. In cut sizes, the number ofSITAS is computed from the specified length and width dimensions andsheet count. For calculating mass, the density of steel for tin mill productsis 7850 kg/m3(see Specification A 6
22、23M).4. Rolling Direction4.1 Double-reduced black plate is relatively brittle and hasvery distinct directional properties. The rolling direction mustbe specified on cut lengths and will be indicated by underliningthe slit (rolling width) dimension. To minimize the flange-cracking hazard when the pro
23、duct is used for can bodies, therolling direction must be around the circumference of the can.5. Surface Finish5.1 Base Metal FinishDouble-reduced black plate is pro-duced with a ground roll finish.5.1.1 7CA smooth finish with grit lines. The surfaceroughness will range from 6 to 25 in. Ra 0.152 to
24、0.635 mRa. This is the standard finish for tin mill products.6. General Requirements for Delivery6.1 Material furnished under this specification shall con-form to the applicable requirements of the current edition ofSpecification A 623 Specification A 623M unless otherwiseprovided herein.SUMMARY OF
25、CHANGESCommittee A01 has identified the location of selected changes to this standard since the last issue(A 650/A 650M - 98) that may impact the use of this standard.A 650/A 650M - 03:(1) Decrease minimum ordered thickness from 0.0055 in. to0.0050 in. 0.140 mm to 0.127 mm in paragraph 1.2 to becons
26、istent with the minimum thickness of like products forA 626/A 626M and A 657/A 657M.(2) Change metric decimal thickness from two significantfigures to three significant figures in paragraph 1.2.ASTM International takes no position respecting the validity of any patent rights asserted in connection w
27、ith any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject to revision at any time by the responsible tec
