1.1 This specification2 covers hot-wrought special quality carbon steel bars and bar size shapes produced to mechanical property requirements and intended for general constructional applications. 1.2 The bars are available in nine strength grades designated 45, 50, 55, 60, 65, 70, 75, 80, and 90 [310, 345, 380, 415, 450, 485, 515, 550, and 620] corresponding to the minimum ultimate tensile strength in ksi [MPa]. The chemical composition is selected by the manufacturer to develop the required mechanical properties. 1.3 Hot-wrought special quality carbon steel bars subject to mechanical property requirements are hot wrought in straight lengths only. Sections and sizes available are covered in Specification A29/A29M. 1.4 Some applications may require one or more of the available designations shown under Supplementary Requirements. Note 1—Merchant-quality hot-wrought carbon steel bars subject to mechanical property requirements are covered in Specification A663/A663M. 1.5 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.

ASTM A955/A955M-14 螺纹及无节不锈钢混凝土钢筋标准规格

1.1 This specification covers deformed and plain stainless-steel bars for concrete reinforcement in cut lengths and coils used in applications requiring resistance to corrosion or controlled magnetic permeability. The standard sizes and dimensions of deformed bars and their numerical designation shall be those listed 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. 1.1.1 Supplementary requirement (S1) of an optional nature is provided. It shall apply only when specified by the purchaser. In order to obtain a controlled magnetic permeability product, steel conforming to Supplementary Requirement S1 should be ordered. 1.2 The chemical composition of the stainless steel alloy shall be selected for suitability to the application involved by agreement between the manufacturer and the purchaser. This is an important consideration in achieving the desired corrosion resistance or controlled magnetic permeability, or both, because these properties are not provided by all stainless steels.Note 1—The alloys shown in Table 2 have found the most use in North America. Other alloys may also provide desired properties; consult with the 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 as Grade 60 [420] and Grade 75 [520], respectively. 1.5 Plain bars in sizes up to and including 2 in. [50.8 mm] in diameter in coils or cut lengths, when ordered, shall be furnished under this specification in Grade 60 [420] and Grade 75 [520], respectively. Bending properties, when required, shall be by agreement between the manufacturer and purchaser. Requirements providing for deformations and marking shall not be applicable to plain bars. 1.6 Weldability of most stainless steel compositions is generally good, however, pre-weld or post-weld procedures, or both, are necessary. Where material is to be welded, a welding procedure suitable for the chemical composition and intended use or service shall be used. Retesting of physical properties should be considered following welding procedures depending upon the steel composition and welding operation involved. Note 2—It is recommended that the user consult the manufacturer for information available from the Nickel Development Institute (NIDI) (Toronto, Canada). 1.7 This specification is applicable for orders in either inch-pound units (as Specification A955) or in SI units (as Specification A955M). 1.8 The values stated in either inch-pound 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 are not exact equivalents; therefore, each system shall be used independently of the other. Com......

Special hardenability limits are also permissible when approved by the purchaser and manufacturer. 1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

Standard Specification for Carbon and Alloy Steel Bars Subject to End-Quench Hardenability Requirements

ASTM A950/A950M-11 熔融结合环氧涂层结构钢H型钢桩及板桩的标准规格

1.1 This specification covers structural steel H-piles and sheet piling with protective fusion-bonded epoxy coating applied by the electrostatic spray, flocking, or fluidized bed process. Note 18212;The coating applicator is identified throughout this specification as the manufacturer. 1.2 Requirements for coatings are contained in Annex A1. 1.3 This specification is applicable for orders in either inch-pound units (as Specification A950) or SI units (as Specification A950M). The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 1.4 This standard does not purport to address any of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
