ASTM A108-13 pdf free.Standard Specification for Steel Bar, Carbon and Alloy, Cold-Finished.
ASTM A108 covers cold-finished carbon and alloy steel bars produced in straight length and coil to chemical compositions. Cold-finished bars are suitable for heat treatment, for machining into components, or for use in the as-finished condition as shafting, or in constructional applications, or for other similar purposes (Note 1). Grades of steel are identified by grade numbers or by chemical composition.
4. Ordering nformation
4.1 Orders for cold-finished steel bar to this specification should include the following items to adequately describe the material:
4.1.1 Name of material
4.1.2 ASTM specification number and date of issue
4.1.3 Chemical composition, or steel grade designation or limits as defined in Specification A29/A29M
4.1.4 Silicon level, if required
4.1.5 Additional machinability-enhancing elements (see Footnote F to Table I of Specification A29/A29M).
4.1.6 Surface Condition(Surface tolerances listed in Table Al.7, Table Al.8, and Table Al.9)
4.1.7 Tolerance Levels (Reference tolerances listed in Table AlI through Table Al.9).
4.1.8 Shape (round, hexagon, square, flat, etc. ) size, and length
4.1.9 Report of heat analysis, if required.
4.1.10 End use.
5. General Requirements
5.1 Material furnished under this specification shall con form to the applicable requirements of the current edition of Specification A29/A29M.
6. Materials and Manufacture
6.1 Feedstock-Cold-finished steel bar shall be produced from hot-wrought carbon or alloy steel bar(Specification A29/A29M), or from hot-wrought rod designated for cold- finished bar (Specification A510/A510M).
7. Chemical Composition
7. 1 Chemical Composition
7. 1. I The chemical analysis of the steel shall conform to that specified in Specification A29/A29M for the steel grade ordered, or to such other limits as may be specified using the standard ranges in Specification A29/A29M.
7. 1.2 Steels may be selected from: Specifications A29/ A29M. A304. A322. A510/A510M. and A576: the SAE Handbook: or the AIST Bar Steels: Steel Product Manual.
7.1.3 When a steels composition cannot be identified by a standard grade number in accordance with 7..I and 7. 1. 2, the limits for each required element may be specified using the chemical ranges shown in the table (Heat Analysis Chemical Ranges and Limits of Carbon Steel Bars)of SpecificationA29/A29M.
