(Specification)Standard Specification for Deformed and Plain, Low-carbon, Chromium, Steel Bars for Concrete Reinforcement
Standard Specification for Deformed and Plain, Low-carbon, Chromium, Steel Bars for Concrete Reinforcement
ABSTRACT
This specification covers low-carbon, chromium, steel bars, deformed and plane for concrete reinforcement in cut lengths and coils. The bars shall be rolled from properly identified heats of mold cast or strand cast steel using the basic oxygen, electric-furnace, or open-hearth process. Heat analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, chromium, manganese, nitrogen, phosphorus, sulfur, and silicon. Steel specimens shall also undergo deformations test, tensile test, and bend test. Steel specimens shall conform to required values of tensile strength, yield strength, stress, and elongation. Final products shall be marked by a tag.
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.2TABLE 1 Deformed Bar Designation Numbers, Nominal Weights [Masses], Nominal Dimensions, and Deformation Requirements

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.Note 1—Caution: Designers need to be aware that typical design standards limit the design strength to 80 000 psi [550 MPa], except for prestressing steel and for spiral transverse reinforcement. Members reinforced with bars with yield strengths that are considerably above 80 000 psi [550 MPa] may exhibit behavior that differs from that expected of conventional reinforced concrete members or may require special detailing to ensure adequate performance at service and factored loads.

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
2
tables and figures) shall not be considered as requirements of the specification.
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.
NOTE 1—Caution: Designers need to be aware that typical design standards limit the design strength to 80 000 psi [550 MPa], except for prestressing
steel and for spiral transverse reinforcement. Members reinforced with bars with yield strengths that are considerably above 80 000 psi [550 MPa] may
exhibit behavior that differs from that expected of conventional reinforced concrete members or may require special detailing to ensure adequate
performance at service and factored loads.
1.3 Deformed bars shall have a minimum yield strength and other tensile properties in accordance with Table 2. Hot-rolled plain

2. Requirements covering deformation dimensions and marking are not applicable to plain rounds.
NOTE 2—Welding of the material in this specification should be approached with caution since no specific provisions have been included to enhance
its weldability. When this steel is to be welded, a welding procedure suitable for the chemical composition and intended use or service should be used.
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.
