1.1 This specification covers standard quality cold-finished carbon steel bars produced to chemical compositions. Standard quality 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 Material furnished under this specification shall conform to the applicable requirements of the current edition of Specification A29/A29M.
1.3 Some end uses may require material superior to standard quality involving one or more of the available designations shown under Supplementary Requirements. Supplementary requirements shall apply only when specified individually by the purchaser.
