1. Scope |
1.1 This specification covers deformed and plain axle-steel bars for concrete reinforcement. The standard sizes and dimensions of deformed bars and their number designations shall be those listed in Table 1. 1.1.1 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification. 1.2 Bars are of two minimum yield levels: namely, 40 000 psi [300 MPa] and 60 000 psi [420 MPa], designated as Grade 40 [300] and Grade 60 [420], respectively. 1.3 Plain rounds, in sizes up to and including 2 in. [50.8 mm] in diameter, in coils or cut lengths, when specified for dowels, spirals and structural ties or supports shall be furnished under this specification in Grade 40 [300] and Grade 60 [420]. For ductility properties (elongation and bending), test provisions of the nearest smaller nominal diameter deformed bar shall apply. Requirements providing for deformations and marking shall not be applicable. 1.4 The weldability of the steel is not a requirement of this specification. 1.5 This specification is applicable for orders in either inch-pound units (as Specification A617) or SI units [as Specification A617M]. 1.6 The values stated in either inch-pound units or SI units are to be regarded as 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 independently of the other. Combining values from the two systems may result in nonconformance with the specification. |
