ASTM A706/A706M-05a

Standard Specification for Low-Alloy Steel Deformed and Plain Bars for Concrete Reinforcement

SCOPE
1.1 General—This specification covers deformed and plain low-alloy steel bars in cut lengths or coils for concrete reinforcement intended for applications where restrictive mechanical properties and chemical composition are required for compatibility with controlled tensile property applications or to enhance weldability. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification.
1.2 GradeBars are of a single minimum yield strength level: namely, 60 000 psi [420 MPa], designated as Grade 60 [420].
1.3 Plain rounds, in sizes up to and including 2 1/2 in. [63.5 mm] in diameter in coils or cut lengths, when ordered, shall be furnished under this specification. For ductility properties (elongation and bending), test provisions of the nearest smaller nominal diameter deformed bar size shall apply.
1.4 Controlled Tensile Properties—This specification limits mechanical properties (Table 2) to provide the desired yield/tensile properties for controlled tensile property applications.
1.5 Welding—This specification limits chemical composition (6.2) and carbon equivalent (6.4) to enhance the weldability of the material. When steel is to be welded, a welding procedure suitable for the chemical composition and intended use or service should be used. The use of the latest edition of ANSI/AWS D1.4 is recommended. This document describes the proper selection of the filler metals, preheat/interpass temperatures, as well as, performance and procedure qualification requirements.
1.6 This specification is applicable for orders in either inch-pound units (Specification A 706) or in SI units [Specification A 706M].
1.7 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 this specification.
