Standard Specification for Castings, Steel and Alloy, Common Requirements, for General Industrial Use

ABSTRACT
This specification covers a group of common requirements that, unless covered by the individual product specification in another ASTM document, applies to steel and alloy castings for use in general industrial applications. Materials shall be produced by open-hearth or electric furnace process with or without separate refining, such as argon-oxygen-decarburization (AOD), and then consequently heat treated in the working zone. Castings shall receive heat and product analysis to evaluate their conformance to chemical composition requirements. Mechanical requirements shall also be assessed. The surfaces of castings shall be free of adhering sand, scale, cracks, hot tears, and other surface discontinuities. Repair welding may be performed as required.
SCOPE
1.1 This specification covers a group of requirements that are mandatory requirements of the following steel casting specifications issued by ASTM. If the product specification specifies different requirements, the product specification shall prevail.

1.2 This specification also covers a group of supplementary requirements that may be applied to the above specifications as indicated therein. These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order.  
1.3 The requirements of the individual material specification and this general specification shall prevail in the sequence named.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
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 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
of the standard as published by ASTM is to be considered the official document.
