Abstract
This specification covers carbon and low-alloy steel castings. The steel specimens shall be heat treated and shall conform to the required values of austenitizing temperature and tempering temperature. The steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, and molybdenum. Tensile tests shall be performed and the steel specimens shall conform to the required values of tensile strength, yield strength, and elongation.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers carbon and low-alloy steel castings having chemical analyses similar to that of the standard wrought grades.
1.2 Several classes are covered and are designated by chemical composition as shown in Table 1.
1.3 Options for tensile properties are shown in Tables 2 and 3.
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.
1.4.1 Within the text, the SI units are shown in brackets.
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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
