SUPERSEDED (see Active link, below)
ASTM A1035 / A1035M
1. Scope
1.1 This specification covers low-carbon, chromium, steel bars, deformed and plain for concrete reinforcement in cut lengths and coils. 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 which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 2

1.2 Bars are of two minimum yield strength levels as defined in 9.2 : namely, 100?000 psi [690 MPa], and 120?000 [830 MPa] designated as Grade 100 [690] and Grade 120 [830], respectively.
1.3 Deformed bars shall have a minimum yield strength and other tensile properties in accordance with Table 2 . Hot-rolled plain rounds in sizes up to and including 2.25 in. [57.2 mm] in diameter in coils or cut lengths when specified for dowels, spirals, structural ties or bar supports shall be furnished under this specification and shall also meet the tensile properties requirements of Table 2 . Ductility properties for plain rounds shall be those of the nearest smaller nominal diameter deformed bar size in Table 2 . Requirements covering deformation dimensions and marking are not applicable to plain rounds.

1.4 Requirements for alternate bar sizes are presented in Annex A1 . The requirements in Annex A1 only apply when specified by the purchaser (see 4.1.10 ).
1.5 This specification is applicable for orders in either inch-pound units (as Specification A1035) or in SI units (as Specification A1035M).
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.
