Anotace textu normy ASTM A311/A311M-04(2020) :
This specification covers cold-drawn, stress-relieved carbon steel bars subject to mechanical property requirements. The bars are furnished in two classes, A and B. Class A are normal-draft cold-drawn and stress-relieved rounds, squares, hexagons, and flats. Class B are heavy-draft cold-drawn and stress-relieved rounds and hexagons. The steel shall be made by one or more of the following primary processes: open-hearth, basic-oxygen, or electric-furnace. The cast or heat analysis shall conform to the chemical composition requirements specified. Tension test shall be made to conform to the requirements specified.

| 1. Scope | ||||||||
|
1.1 This specification covers two classes, nine grades, and four conditions of stress-relieved cold-drawn carbon steel bars produced to mechanical property requirements. One class, B, is cold drawn with higher than normal (heavy) drafts to provide higher strength levels, and four grades provide improved machinability. 1.2 Supplementary Requirements, S1 through S6, of an optional nature are provided. 1.3 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 necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 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. |
