(Specification)Standard Specification for Continuous Galvanizing Grade (CGG) Zinc Alloys for Hot-Dip Galvanizing of Sheet Steel
Standard Specification for Continuous Galvanizing Grade (CGG) Zinc Alloys for Hot-Dip Galvanizing of Sheet Steel
ABSTRACT
This specification covers grades of zinc alloys, commonly known as continuous galvanizing grade (CGG) alloys that contain aluminum, or aluminum and lead and that are used in continuous hot-dip galvanizing of steel sheet. CGG alloy shall be tested and conform to the chemical composition requirements as determined by chemical analysis on samples taken. CGG alloy castings shall be free of undue surface oxide, adhering foreign matter, and any flash that would interfere with handling and use. Samples obtained during casting, drilling or sawing shall be analyzed individually and the average of the individual determinations for the samples from the lot shall be reported as the analysis of the lot.
SCOPE
1.1 This specification covers grades of zinc alloys, commonly known as Continuous Galvanizing Grade (CGG) alloys that contain aluminum, or aluminum and lead, that are used in continuous hot-dip galvanizing of steel sheet. The compositions for CGG grades made from primary zinc are shown in Table 1. Exceptions for grades made from secondary zinc are found in footnote C.
1.2 CGG alloys specified in Specification B852 are used in continuous hot-dip galvanizing of steel sheet to produce product, as specified in Specification A653/A653M.
1.3 Other alloy compositions not included in B852, and as may be agreed upon between the producer and the user, may be used for continuous galvanizing.
1.4 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.
1.5 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 and health practices, and determine the applicability of regulatory limitations prior to use.
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 document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
