ASTM A615/A615M-20,Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement.ASTM A615/A615M-20 pdf free download.
ASTM A615/A615M-20 covers deformed and plain carbon-steel bars in cut lengths and coils for concrete reinforcement. Annex A2 of this specification covers deformed bars for use for other applications. Steel bars containing alloy additions, such as with the Association for Iron and Steel Technology and the Society of Automotive Engineers series of alloy steels, are permitted if the resulting product meets all the other requirements of this specification. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1.

5. Material and Manufacture
5.I The bars shall be rolled from properly identified heats of mold-cast or strand-cast steel. The steel shall be made by any commercially accepted process.
6. Chemical Composition
6.1 The chemical analysis of each heat of steel shall be determined in accordance with Test Methods. Practices. and Terminology A751. The manufacturer shall make the analysis test samples taken preferably during the pouring of the heat.
The percentages of carbon, manganese, phosphorus, and sulfur shall be determined. The phosphorus content thus determined shall not exceed 0.06%.
6.2 A product check, for phosphorus, made by the purchaser shall not exceed that specified in 6.1 by more than 25 %.
7. Requirements for Deformations
7.I Deformations shall be spaced along the bar at substantially uniform distances. The deformations on opposite sides of
the bar shall be similar in size, shape, and pattern.
