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 deformed and plain low-carbon, chromium, steel bars, in cut lengths and coils for concrete reinforcement. These bars are furnished in three alloy types depending on the chromium range content. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1.2  
1.2 Bars are of two minimum yield strength levels as defined in 9.2: namely, 100 000 psi [690 MPa], and 120 000 psi [830 MPa] designated as Grade 100 [690] and Grade 120 [830], respectively.  
1.3 Bars are furnished to three different chemical compositions, designated as Alloy Type CL, CM, and CS. Chemical compositions are shown in Table 2.  
1.4 Plain bars, in sizes up to and including 2.25 in. [57.2 mm] 21/2 in. [63.5 mm] in diameter in coils and cut lengths, when ordered shall be furnished under this specification in Grade 100 [690] and Grade 120 [830]. For ductility properties (elongation and bending), test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Requirements providing for deformations and marking shall not be applicable.
Note 1: 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.
Note 2: Designers need to be aware that design codes and specifications may not recognize the use of the No. 20 [64] bar, the largest bar size included in this specification. Structural members reinforced with No. 20 [64] bars may require approval of the building official or other appropriate authority and require special detailing to ensure adequate performance at service and factored loads.  
1.5 Requirements for alternate bar sizes are presented in Annex A1. The requirements in Annex A1 only apply when specified by the purchaser (see 4.2.4).  
1.6 A supplementary requirement (S1) is provided for use where bend testing of bar designation Nos. 14 and 18 [43, 57], and bar designation Nos. 40, 50, and 60 in Annex A1, is required by the purchaser. The supplementary requirement applies only when specified in the purchase order.  
1.7 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.  
1.8 This specification is applicable for orders in either inch-pound units (as Specification A1035) or in SI units (as Specification A1035M).  
1.9 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

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

ABSTRACT
This specification covers deformed and plain low-alloy steel bars in cut lengths or coils for concrete reinforcement intended for applications. Restrictive mechanical properties and chemical composition are required for compatibility with controlled tensile property applications or to enhance weldability. The steel shall be electric-furnace, basic-oxygen, or open-hearth processed. Tension test, bend test, and one set of dimensional property tests including bar weight and spacing, height, and gap of deformations shall be made of each bar size rolled from a heat. All tests and inspection shall be made at the place of manufacture prior to shipment, unless otherwise specified, and shall be conducted so as not to interfere unnecessarily with the operation of the works. A retest shall be provided when the specimen fails to meet the strength and elongation property requirements of the specification.
SCOPE
1.1 General—This specification covers deformed and plain low-alloy steel bars in cut lengths and 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.  
1.2 Grade—Bars are of three minimum yield strength levels: namely, 60 000 psi [420 MPa], 80 000 psi [550 MPa], and 100 000 psi [690 MPa] designated as Grade 60 [420], Grade 80 [550], and Grade 100 [690], respectively.  
1.3 Plain bars, in sizes up to and including 21/2 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. Requirements providing for deformations and marking shall not be applicable.  
1.4 Controlled Tensile Properties—This specification limits tensile 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 this 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 AWS D1.4/D1.4M is recommended. The AWS D1.4/D1.4M Welding Code describes the proper selection of the filler metals, preheat/interpass temperatures, as well as, performance and procedure qualification requirements.
Note 1: As a result of the 117 000 psi minimum tensile strength for Grade 100 [690], users of this specification should be aware that ACI 318 Type 1 mechanical splice requirements of 125 % of specified yield strength requirements in tension and compression, found in many acceptance criteria, may result in an invalid mechanical splice qualification or verification test when the tensile strength of the bar is between 117 000 psi and 125 000 psi.  
1.6 Annex A2 describes the methods for determination of uniform elongation (Elu). Annex A2 is mandatory when Supplementary Requirement S1 is specified by the purchaser (see 4.2.6).  
1.7 Requirements for alternate bar sizes are presented in Annex A1. The requirements in Annex A1 only apply when specified by the purchaser (see 4.2.5).  
1.8 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables, shall not be considered as requirements of this specification.  
1.9 This specification is applicable for orders in either inch-pound units (Specification A706) or in SI units [Specification A706M].  
1.10 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated ...

ASTM A1060/A1060M-22(Specification)
Standard Specification for Zinc-Coated (Galvanized) Steel Welded Wire Reinforcement, Plain and Deformed, for Concrete

SCOPE
1.1 This specification covers zinc-coated steel welded wire reinforcement, plain and deformed, or a combination of deformed and plain wires, for reinforcement of concrete, in sizes not less than 0.080 in. [2.03 mm] and over nominal diameter for plain wire and 0.113 in. [2.87 mm] and over for deformed wire.  
1.2 This specification is intended to be applicable to cold-worked wire, drawn or rolled, plain or deformed, coated in a continuous process.  
1.3 An alternative to a continuous coating process of wire before fabrication is a hot-dip process, where the welded wire reinforcement is immersed in a bath of molten zinc.
Note 1: Data on the corrosion resistance of galvanized steels in concrete are limited. The user is cautioned that the laboratory testing performed on this material has been insufficient and may not accurately reflect the performance of the material when embedded in concrete as reinforcement.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A1064/A1064M-22(Specification)
Standard Specification for Carbon-Steel Wire and Welded Wire Reinforcement, Plain and Deformed, for Concrete

ABSTRACT
This specification covers the material, dimensional and mechanical property requirements for plain and deformed steel wire and welded wire reinforcements produced from hot-rolled rods that are to be used for the reinforcement of concrete. Tension test procedures are detailed for each type of wire reinforcement to examine their adherence to specified tensile strength, yield strength, and reduction of area requirements.
SCOPE
1.1 This specification covers carbon-steel wire and welded wire reinforcement produced from hot-rolled rod to be used for the reinforcement of concrete. The steel wire is cold-worked, drawn or rolled, plain (non-deformed, as-drawn or galvanized), or deformed. Welded wire reinforcement is made from plain or deformed wire, or a combination of plain and deformed wire. Common wire sizes and dimensions are given in Table 1, Table 2, Table 3, and Table 4. Actual wire sizes are not restricted to those shown in the tables.    
Note 1: Welded wire for concrete reinforcement has historically been described by various terms: welded wire fabric, WWF, fabric, and mesh. The wire reinforcement industry has adopted the term welded wire reinforcement (WWR) as being more representative of the applications of the products being manufactured. Therefore, the term welded wire fabric has been replaced with the term welded wire reinforcement in this specification and in related specifications.  
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text the SI units are shown in brackets (except in Table 2 and Table 4). The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with this specification.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Steel Fibers for Fiber-Reinforced Concrete

ABSTRACT
This specification covers steel fibers intended for use in fiber-reinforced concrete. The fibers shall be straight or deformed and of Types I (cold-drawn wire), II (cut sheet), III (melt-extracted), IV (mill cut), and V ( modified cold-drawn wire). Tensile and bend tests of randomly-selected finished fibers shall be performed. Measurement of dimensions shall be performed and values should conform to permissible variations of length, nominal length, diameter, equivalent diameter, aspect ratio, and nominal aspect ratio. Guidelines for inspection, rejection, rehearing, certification, and packaging are also given.
SCOPE
1.1 This specification covers minimum requirements for steel fibers intended for use in fiber-reinforced concrete. Five types of steel fibers for this purpose are defined as pieces of smooth or deformed cold-drawn wire; smooth or deformed cut sheet; melt-extracted fibers; mill-cut or modified cold-drawn wire steel fibers that are sufficiently small to be dispersed at random in a concrete mixture.  
1.2 This specification provides for measurement of dimensions, tolerances from specified dimensions, and required minimum physical properties, and prescribes testing procedures to establish conformance to these requirements.  
1.3 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of a conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by the waiving of a test requirement or by making a test requirement less stringent.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Steel specimens shall also undergo tensile tests and shall conform to required values of tensile strength, yield strength, and elongation. Steel samples shall also undergo deformation test, tension test and bend tests. Final products shall be marked by a tag.
SCOPE
1.1 This specification covers deformed and plain carbon-steel bars in cut lengths and coils for concrete reinforcement. Annex A2 of this specification covers deformed bars for use for other applications. Steel bars containing alloy additions, such as with the Association for Iron and Steel Technology and the Society of Automotive Engineers series of alloy steels, are permitted if the resulting product meets all the other requirements of this specification. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1.    
1.2 Unless specified for use for other applications in Annex A2, bars are of four minimum yield strength levels: namely, 40 000 psi [280 MPa], 60 000 psi [420 MPa], 80 000 psi [550 MPa], and 100 000 psi [690 MPa], designated as Grade 40 [280], Grade 60 [420], Grade 80 [550], and Grade 100 [690], respectively.
Note 1: Grade 100 [690] reinforcing bars were introduced in this specification in 2015. In contrast to the lower grades, which have ratios of specified tensile strength to specified yield strength that range from 1.25 to 1.50, Grade 100 [690] reinforcing bars have a ratio of specified tensile strength to specified yield strength of 1.15. Users of this specification should be aware that there will, therefore, be a lower margin of safety and reduced warning of failure following yielding when Grade 100 [690] bars are used in structural members where strength is governed by the tensile strength of the reinforcement, primarily in beams and slabs. As a result of the lower specified tensile strength to specified yield strength ratio of 1.15 for Grade 100 [690], users of this specification should be aware that ACI 318 Type 1 mechanical and welded splice requirements found in many acceptance criteria of 125 % of specified yield strength requirements in tension and compression are not applicable to Grade 100 [690]. Mechanical and welded splices should meet a minimum specified tensile strength of 115 000 psi [790 MPa] for Grade 100 [690].
Note 2: Users of this specification need to be aware that consensus design codes and specifications may not recognize the use of the No. 20 [64] bar, the largest bar included in this specification. Structural members reinforced with No. 20 [64] bars may require approval of the building official or other appropriate authority and require special detailing to ensure adequate performance at service and factored loads.  
1.3 Plain bars, in sizes up to and including 21/2 in. [63.5 mm] in diameter in coils or cut lengths, when ordered shall be furnished under this specification in Grade 40 [280], Grade 60 [420], Grade 80 [550], and Grade 100 [690]. For ductility properties (elongation and bending), test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Requirements providing for deformations and marking shall not be applicable.  
Note 3: 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. T...

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

ABSTRACT
This specification covers deformed and plain low-alloy steel bars in cut lengths or coils for concrete reinforcement intended for applications. Restrictive mechanical properties and chemical composition are required for compatibility with controlled tensile property applications or to enhance weldability. The steel shall be electric-furnace, basic-oxygen, or open-hearth processed. Tension test, bend test, and one set of dimensional property tests including bar weight and spacing, height, and gap of deformations shall be made of each bar size rolled from a heat. All tests and inspection shall be made at the place of manufacture prior to shipment, unless otherwise specified, and shall be conducted so as not to interfere unnecessarily with the operation of the works. A retest shall be provided when the specimen fails to meet the strength and elongation property requirements of the specification.
SCOPE
1.1 General—This specification covers deformed and plain low-alloy steel bars in cut lengths and 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.  
1.2 Grade—Bars are of two minimum yield strength levels: namely, 60 000 psi [420 MPa] and 80 000 psi [550 MPa], designated as Grade 60 [420] and Grade 80 [550], respectively.  
1.3 Plain bars, in sizes up to and including 21/2 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. Requirements providing for deformations and marking shall not be applicable.  
1.4 Controlled Tensile Properties—This specification limits tensile 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 this 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 AWS D1.4/D1.4M is recommended. The AWS D1.4/D1.4M Welding Code describes the proper selection of the filler metals, preheat/interpass temperatures, as well as, performance and procedure qualification requirements.  
1.6 Requirements for alternate bar sizes are presented in Annex A1. The requirements in Annex A1 only apply when specified by the purchaser (see 4.2.5).  
1.7 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables, shall not be considered as requirements of this specification.  
1.8 This specification is applicable for orders in either inch-pound units (Specification A706) or in SI units [Specification A706M].  
1.9 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with this specification.  
1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles f...
