1、Designation: A924/A924M 141Standard Specification forGeneral Requirements for Steel Sheet, Metallic-Coated bythe Hot-Dip Process1This standard is issued under the fixed designation A924/A924M; the number immediately following the designation indicates the yearof original adoption or, in the case of
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.1NOTEIn Table 5, footnotes A and B, reference to Table 14 was corrected to Table 15 in April 2016.1. Scope*1
3、.1 This specification covers the general requirements that,unless otherwise specified in the product specification, apply tosteel sheet in coils and cut lengths, metallic-coated on continu-ous lines by the hot-dip process. The product is intended forapplications requiring corrosion resistance. The p
4、roduct speci-fications contain requirements for specific strength levels, heatresistance, paintability, or formability, or a combinationthereof.1.2 Subject to individual product specification provisions,steel sheet is available as Commercial Steel (CS) Types A, B,and C, Forming Steel (FS), Drawing S
5、teel (DS), Deep DrawingSteel (DDS), Extra Deep Drawing Steel (EDDS), High Tem-perature Steel (HTS), Structural Steel (SS), and High StrengthLow Alloy Steel (HSLAS). Steel sheet is produced with thefollowing metallic coatings. Specific information on each ofthe following is contained in the individua

8、 individual product specifica-tions. Except for differentially coated sheet, the coating isalways expressed as the total coating of both surfaces.1.5 In case of any conflict in requirements, the requirementsof the individual product specifications shall prevail over thoseof this general specificatio
9、n.1.6 The purchaser is permitted to specify additional require-ments that do not negate any of the provisions of this generalspecification or of the individual product specifications. Suchadditional requirements, the acceptance of which are subject tonegotiation with the supplier, shall be included
10、in the orderinformation.1.7 For purposes of determining conformance with thisspecification and the various product specifications referencedin 1.3, values shall be rounded to the nearest unit in theright-hand place of figures used in expressing the limitingvalues (except to the nearest 5 MPa for SI
11、strength values) inaccordance with the rounding method of Practice E29.1.8 Metallic-coated steel sheet covered by this specificationis produced to thickness requirements expressed to 0.001 in.0.01 mm for both coils and cut lengths. The thickness is thetotal of the base steel and the coating.1.9 The
12、text of this specification references notes andfootnotes that provide explanatory material. These notes andfootnotes (excluding those in tables and figures) shall not beconsidered as requirements of the specification.1.10 The values stated in inch-pound units or SI units are tobe regarded separately
13、 as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system are notexact equivalents; therefore, each system must be used inde-pendently of the other.1.11 This specification and some of the applicable productspecifications are expressed in both inch-pound and S
14、I units.However, unless the order specifies the applicable “M” speci-fication designation (SI units), the product shall be furnished toinch-pound units.1.12 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of th
