(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 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 (A) The nominal dimensions of a deformed bar are equivalent to those of a plain round bar having the same weight [mass] per foot [metre] as the deformed bar.(B) Refer to Note 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. (A) Maximum unless range is indicated; percentages refer to weight [mass] percentages.
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 specif...
