1、Designation: A955/A955M 15Standard Specification forDeformed and Plain Stainless-Steel Bars for ConcreteReinforcement1This standard is issued under the fixed designation A955/A955M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, t
2、he year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers deformed and plain stainless-steel bars for concrete reinforcement in cut length
3、s and coilsused in applications requiring resistance to corrosion or con-trolled magnetic permeability. The standard sizes and dimen-sions of deformed bars and their numerical designation shall bethose listed in Table 1. The text of this specification referencesnotes and footnotes which provide expl
4、anatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.1.1 Supplementary requirement (S1) of an optional natureis provided. It shall apply only when specified by the purchaser.In order to obtain a controlled ma
5、gnetic permeability product,steel conforming to Supplementary Requirement S1 should beordered.1.2 The chemical composition of the stainless steel alloyshall be selected for suitability to the application involved byagreement between the manufacturer and the purchaser. This isan important considerati
6、on in achieving the desired corrosionresistance or controlled magnetic permeability, or both, be-cause these properties are not provided by all stainless steels.NOTE 1The alloys shown in Table 2 have found the most use in NorthAmerica. Other alloys may also provide desired properties; consult withth
7、e manufacturer for stainless steel alloy properties and availability.1.3 Requirements for the relative deformation area of three-sided deformed bars are contained in Annex A4.1.4 Bars are of two minimum yield strength levels, namely,60 000 420 MPa and 75 000 psi 520 MPa, designated asGrade 60 420 an
8、d Grade 75 520, respectively.1.5 Plain bars in sizes up to and including 2 in. 50.8 mmin diameter in coils or cut lengths, when ordered, shall befurnished under this specification in Grade 60 420 and Grade75 520, respectively. Bending properties, when required,shall be by agreement between the manuf
9、acturer and purchaser.Requirements providing for deformations and marking shallnot be applicable to plain bars.1.6 Weldability of most stainless steel compositions isgenerally good, however, pre-weld or post-weld procedures, orboth, are necessary. Where material is to be welded, a weldingprocedure s
10、uitable for the chemical composition and intendeduse or service shall be used. Retesting of physical propertiesshould be considered following welding procedures dependingupon the steel composition and welding operation involved.NOTE 2It is recommended that the user consult the manufacturer forinform
11、ation available from the Nickel Development Institute (NIDI)(Toronto, Canada).1.7 This specification is applicable for orders in eitherinch-pound units (as Specification A955) or in SI units (asSpecification A955M).1.8 The values stated in either inch-pound or SI units are tobe regarded separately a
12、s standard. Within the text, the SI unitsare shown in brackets. The values stated in each system are notexact equivalents; therefore, each system shall be used inde-pendently of the other. Combining values from the two systemsmay result in nonconformance with the standard.1.9 This standard does not
13、purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
