ASTM A576-23

Standard Specification for Steel Bars, Carbon, Hot-Wrought, Special Quality

ABSTRACT
This specification covers hot-wrought special quality carbon steel bars. Special quality bar applications include forging, heat treating, cold drawing, machining, and many structural uses. The steel shall be made by one or more of the following primary processes: open-hearth, basic-oxygen, or electric furnace. The heat analysis shall conform to the requirements for chemical composition specified.
SCOPE
1.1 This specification covers hot-wrought special quality carbon steel bars. Special quality bar applications include forging, heat treating, cold drawing, machining, and many structural uses. A guide for the selection of steel bars is contained in Practice A400.  
1.2 The bars shall be furnished in the grades specified in Table 1. Sections and sizes of bar steel available are covered in Specification A29/A29M. Hot-wrought special quality carbon steel bars are produced in cut lengths and coils; the manufacturer should be consulted regarding sections and sizes available in coils, produced to a chemical composition.
