ASTM A108-13

Standard Specification for Steel Bar, Carbon and Alloy, Cold-Finished

ABSTRACT
This specification covers cold-finished carbon and alloy steel bars for heat treatment, machining into components, or for as-finished condition as shafting or in constructional applications. The steel materials shall be cold drawn, turned, ground, polished, hot wrought, cold rolled, and heat treated. The steel specimens shall undergo chemical analysis.
SCOPE
1.1 This specification 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.Note 1—A guide for the selection of steel bars is contained in Practice A400.  
1.2 Some end uses may require one or more of the available designations shown under Supplementary Requirements. Supplementary requirements shall apply only when specified individually by the purchaser.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
