1、Designation: A924/A924M 16a1Standard 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.1NOTESummary of Changes reinstated editorially in June 2016.1. Scope*1.1 This specification covers the gene
3、ral 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 product speci-fications contain requir
4、ements 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 Steel (DS), Deep DrawingSteel (DDS), E
5、xtra 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 individual product specifica-tion:1.2.1 Zinc o

Except for differentially
8、 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 specification.1.6 The purchaser is permitted to specify additional require
9、-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 in the orderinformation.1.7 For purposes of determining confor

11、tice 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 text of this specification references notes andfootnotes that
12、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 as standard. Within the text, the SI unitsare shown in bracke
13、ts. 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 SI units.However, unless the order specifies the applicable “M”
