ASTM A913/A913M-19 淬火和自回火工艺（QST）生产的高强度低合金钢结构质量标准规范

1.1 This specification covers high-strength low-alloy structural steel shapes in Grades 50 [345], 60 [415], 65 [450], 70 [485], and 80 [550], produced by the quenching and selftempering process (QST). The shapes are intended for riveted, bolted or welded construction of bridges, buildings and other structures. 1.2 The QST process consists of in line heat treatment and cooling rate controls which result in mechanical properties in the finished condition that are equivalent to those attained using heat treating processes which entail reheating after rolling. A description of the QST process is given in Appendix X1. 1.3 Due to the inherent characteristics of the QST process, Grade 50 [345], 60 [415], 65 [450], and 70 [485] shapes shall not be formed nor post weld heat treated at temperatures exceeding 1100°F [595°C] and Grade 80 [550] shapes shall not be formed nor post weld heat treated at temperatures exceeding 1000°F [540°C]. 1.4 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability. 1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification. 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.
