This specification covers two types of commercial rolled zinc. Type I are coils or sheets cut from strip rolled zinc, and Type II are zinc plates such as boiler and hull plates produced by any rolling method. The products shall be produced by casting, rolling, and other processes found in mill product plant. The material shall be tested and conform to the required chemical composition. The testing of wrought zinc for determination of tensile properties shall be conducted. The testing of zinc for hardness shall be made on a Rockwell superficial hardness tester or on a microhardness tester. The determination of chemical composition shall be performed by either an appropriate chemical method or by optical emission spectrographic methods.1.1 This specification covers two types of commercial rolled zinc as described in 1.2. It should be understood that the specification is general. Any closer limitations on permissible variations shall be a matter of agreement between the supplier (manufacturer) and the purchaser.1.2 Rolled zinc is furnished in two types as follows:1.2.1 Type A—Coils or sheets cut from strip (ribbon) rolled zinc and1.2.2 Type B—Zinc plates such as boiler and hull plates produced by any rolling method.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers hot-rolled and cold-rolled drawing alloy steel sheets and strips for applications involving severe cold plastic deformation such as deep drawn or severely formed parts. Materials may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein, in coils or cut lengths. Unless otherwise specified, specimens shall be heat treated by spheroidize annealing. Materials shall be tested and conform to specified values of chemical composition, metallurgical structure or microstructure, tensile strength, elongation, and Rockwell hardness. Unless otherwise specified, hot-rolled specimens shall be surface finished by descaling and oiling, and furnished with mill edge. While, cold-rolled specimens shall have a commercial dull matte surface finish and be oiled, and furnished with cut edge for sheets, and No. 3 edge for strips.1.1 This specification covers hot-rolled and cold-rolled drawing alloy-steel sheet and strip. Material of this quality is produced principally for applications involving severe cold plastic deformation such as deep drawn or severely formed parts. This steel is produced by a closely controlled steel-making practice designed to assure internal soundness, relative uniformity of chemical composition, and freedom from injurious imperfections.1.2 The material covered by this specification may be furnished in several conditions, heat treatments, surface finishes, and edges, as specified herein, in coils or cut lengths.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers hot-rolled and cold-rolled alloy steel sheet and strip. The steel materials shall be melt processed, hot rolled, cold rolled, and heat treated. Cast or heat analysis and product analysis shall be performed wherein the specimens shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, vanadium, tungsten, and aluminum. The steel materials shall conform to the required metallurgical structure and yield strength. The types of edges procurable in the steel materials are as follows: (1) mill edge; (2) cut edge; (3) square edge; and (4) rounded edge.1.1 This specification covers a group of common requirements that, unless otherwise specified in the material specification, apply to hot-rolled and cold-rolled alloy steel sheet and strip under each of the following specifications: A506, A507, and A873/A873M.1.2 In case of any conflict in requirements, the requirements of the individual material specification shall prevail over those of this general specification.1.3 The purchaser may specify additional requirements which do not negate any of the provisions of this general specification or of the individual material specification. Such additional requirements, the acceptance of which are subject to negotiation with the supplier, must be included in the order information (see 4.1.9).1.4 For purposes of determining conformance with this specification and the various material specifications referenced in 1.1, values shall be rounded to the nearest unit in the right-hand place of figures used in expressing the limiting values in accordance with the rounding provisions of Test Methods and Definitions A370 and Test Methods, Practices, and Terminology A751.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the standard for hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. The material shall be furnished in several conditions: heat treatments such as hot-rolling and cold rolling; surface conditions; and edges, as specified herein, in coils or cut lengths. Heat analysis shall be performed on the material and shall conform to the required chemical compositions for carbon, manganese, phosphorus, sulfur, silicon, copper, nickel, chromium, molybdenum, and vanadium. Materials in the annealed, normalized, or normalized-and-tempered condition shall be capable of meeting the longitudinal bend test requirements. Two tension tests and two hardness tests shall be made from coupons obtained from each heat (cast) and heat treatment lot.1.1 This specification covers hot-rolled and cold-rolled alloy and structural alloy-steel sheet and strip. Alloy steel is furnished to chemical composition requirements and is intended primarily for general or miscellaneous use where bending and moderate forming is a requirement. Structural alloy steel is furnished to chemical composition requirements and to specific mechanical property requirements which may include tension tests, hardness tests, or other commonly accepted mechanical tests.1.2 If material of a higher degree of uniformity of internal soundness and freedom from surface imperfections is required, reference should be made to Specification A507.1.3 Alloy and structural alloy-steel sheet and strip are not produced to internal cleanliness requirements. Normally surface imperfections are not objectionable, and a good finish is not a prime requirement.1.4 The formability of structural alloy steel decreases with increasing yield strength or hardness. Therefore, product design in relation to the mechanical properties of the grade used must be considered.1.5 The material covered by this specification may be furnished in several conditions: heat treatments, surface conditions, and edges, as specified herein, in coils or cut lengths.1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
