Designation: A 29/A 29M 04 Standard Specifi cation for Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements for1 This standard is issued under the fi xed designation A 29/A 29M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. 1. Scope* 1.1 This specifi cation2covers a group of common require- ments which, unless otherwise specifi ed in the purchase order or in an individual specifi cation, shall apply to carbon and alloy steel bars under each of the following ASTM specifi cations (or under any other ASTM specifi cation which invokes this specifi cation or portions thereof): Title of Specifi cationASTM DesignationA Hot-Rolled Carbon Steel Bars: Steel Bars, Carbon, Quenched and TemperedA 321 Steel Bars and Shapes, Carbon Rolled from “T RailsA 499 Steel Bars, Carbon, Merchant Quality, M-GradesA 575 Steel Bars, Carbon, Hot-Wrought, Special QualityA 576 Steel Bars, Carbon, Merchant Quality, Mechanical Properties A 663 Steel Bars, Carbon, Hot-Wrought, Special Quality, Me- chanical Properties A 675 Steel Bars for Springs, Carbon and AlloyA 689 Cold-Finished Carbon Steel Bars: Steel Bars, Carbon, Cold-Finished, Standard QualityA 108 Stress-Relieved Steel Bars Subject to Mechanical Property Requirements, Cold-Drawn Carbon A 311/A 311M Hot-Rolled Alloy Steel Bars: Steel Bars, Alloy, Standard GradesA 322 Steel Bars, Alloy, Subject to End-Quench Hardenability Requirements A 304 Steel Bars, Alloy, Hot-Wrought or Cold-Finished, Quenched and Tempered A 434 Steel Bars, Alloy, Hot-Wrought, for Elevated Tempera- ture or Pressure-Containing Parts, or Both A 739 Cold-Finished Alloy Steel Bars: Steel Bars, Alloy, Hot-Rolled or Cold-Finished, Quenched and Tempered A 434 Steel Bars, Carbon, Hot-Wrought or Cold-Finished, Special Quality, for Pressure Piping Components A 696 A These designations refer to the latest issue of the respective specifi cations, which appear either in theAnnual Book of ASTM Standards, Vol 01.05, or as reprints obtainable from ASTM. 1.2 In case of any confl ict in requirements, the requirements of the purchase order, the individual material specifi cation, and this general specifi cation shall prevail in the sequence named. 1.3 The values stated in inch-pound units or SI units are to be regarded as the 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 inde- pendently of the other. Combining values from the two systems may result in nonconformance with the specifi cation. 1.4 For purposes of determining conformance to this speci- fi cation and the various material specifi cations referenced in 1.1, dimensional values shall be rounded to the nearest unit in the right-hand place of fi gures used in expressing the limiting values in accordance with the rounding method of Practice E 29.

B When silicon is required, the following ranges and limits are commonly specifi ed: 0.10 %, max, 0.10 % to 0.20 %, 0.15 % to 0.35 %, 0.20 % to 0.40 %, or 0.30 % to 0.60 %. C Copper can be specifi ed when required as 0.20 % minimum. D When lead is required as an added element to a standard steel, a range of 0.15 to 0.35 % inclusive is specifi ed. Such a steel is identifi ed by inserting the letter “L” between the second and third numerals of the grade designation, for example, 10 L 45. A cast or heat analysis is not determinable when lead is added to the ladle stream. E When boron treatment for killed steels is specifi ed, the steels can be expected to contain 0.0005 to 0.003 % boron. If the usual titanium additive is not permitted, the steels can be expected to contain up to 0.005 % boron. FThe elements bismuth, calcium, selenium, or tellurium may be added as agreed upon between purchaser and supplier. GUnless prohibited by the purchaser, the manganese content may exceed 0.60 % on heat analysis to a maximum of 0.75 %, provided the carbon range on heat analysis has the minimum and maximum reduced by 0.01 % for each 0.05 % manganese over 0.60 %. TABLE 2Grade Designations and Chemical Compositions of Alloy Steel Bars NOTE 1Small quantities of certain elements are present in alloy steels which are not specifi ed or required. These elements are considered as incidental and may be present to the following maximum amounts: copper, 0.35 %; nickel, 0.25 %; chromium, 0.20 % and molybdenum, 0.06 %. NOTE2Where minimum and maximum sulfur content is shown it is indicative of resulfurized steel. NOTE3The chemical ranges and limits shown in Table 2 are produced to product analysis tolerances shown in Table 6. NOTE 4Standard alloy steels can be produced with a lead range of 0.150.35 %. Such steels are identifi ed by inserting the letter “L” between the second and third numerals of the AISI number, for example, 41 L 40. A cast or heat analysis is not determinable when lead is added to the ladle stream.
