The chemical composition of stainless steels must be determined accurately in order to ensure the desired metallurgical properties. This procedure is suitable for manufacturing control and inspection testing.1.1 This test method covers for the atomic emission vacuum spectrometric analysis of stainless steel in solid form by the point-to-plane excitation technique for the following elements in the concentration ranges shown: ElementConcentration Range, % Chromium17.0 to 23.0 Nickel 7.5 to 13.0 Molybdenum 0.01 to 3.0 Manganese 0.01 to 2.0 Silicon 0.01 to 0.90 Copper 0.01 to 0.30 Carbon 0.005 to 0.25 Phosphorus 0.003 to 0.15 Sulfur 0.003 to 0.065 1.2 This test method is designed for the routine analysis of chill-cast disks or inspection testing of stainless steel samples that have a flat surface of at least 13 mm (0.5 in.) in diameter. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials. 1.3 Analytical curves are plotted using the concentration ratio method as shown in Practice E 158. One or more of the reference materials must closely approximate the composition of the specimen. The technique of analyzing reference materials along with unknowns and performing the indicated mathematical corrections may also be used to correct for interference effects and to compensate for errors resulting from instrument drift. A variety of such systems are commonly used. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM A1022/A1022M-07 混凝土加筋用刻痕和普通不锈钢丝和焊接钢丝的标准规范

1.1 This specification covers stainless steel wire and welded wire reinforcement produced from hot-rolled stainless steel rod. The stainless steel wire is cold-worked, drawn or rolled, plain (non-deformed) or deformed or a combination of deformed and plain. It is used as concrete reinforcement for applications requiring resistance to corrosion and/or controlled magnetic permeability. Common wire sizes and dimensions are found in this specification. Actual wire sizes are not restricted to those shown in the tables.1.2 Supplement S1 describes high strength wire, which shall be furnished when specifically ordered. It shall be permissible to furnish high strength wire in place of regular wire if mutually agreed to by the purchaser and supplier. 1.2.1 A supplementary requirement (S2) of an optional nature is provided. It shall apply only when specified by the purchaser. In order to obtain a corrosion tested or controlled magnetic permeability product, steel conforming to Supplementary Requirement S2 should be ordered. 1.3 The chemical composition of the steel (stainless grade) shall be selected for suitability to the application involved by agreement between the manufacturer and the purchaser. Use Specification A 276 for chemical requirements. The UNS designations are to be included with the type number and noted in brackets, i.e. austenitic stainless steels as Type 304 [S30400], 304L [S30403], 316 [S31600], 316L [S31603], 316N [S31651], 316LN [S31653] and duplex stainless steels, Types 2205 [S32205] and 329 [S32900].Note 1Only austenitic and duplex stainless steels are usually recommended for use as reinforcement in concrete because of their high corrosion resistance. Austenitic stainless steels have good general corrosion resistance, strength characteristics which can be improved by cold working, good toughness and ductility properties at low temperatures, and low magnetic permeability. Duplex stainless steels have generally a corrosion resistance greater than that of most austenitic steels and are magnetic. Other stainless steels with different chemical compositions than the series and types mentioned above, may be used for less restrictive applications.1.4 Wire for welded wire reinforcement is generally manufactured at 520 MPa [75 ksi] yield strength level. Other strength levels shall be by agreement between the purchaser and manufacturer.Note 2The term used to refer to yield strength levels are the same as those in ASTM Standards for welded wire reinforcement.1.5 The values stated in 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 A959-07 锻制不锈钢用说明协调标准等级构成的标准指南

It is anticipated that the ASTM Subcommittees A01.06, A01.10, A01.17, A01.22, and A01.28 will use the standard composition limits listed in this guide for the grades identified by the corresponding UNS designation in the product specification unless there is a specific technical justification for doing otherwise. The compositions in this guide shall not be considered as chemical requirements for any particular product until adopted by the subcommittee overseeing that product. Assuming that uniform compositions among the many product standards for stainless steel are desirable, the composition limits provided in this standard are to be used as guides in determining limits for each of the elements included in the total composition of each grade. The composition limits have been established with the intent that each product subcommittee will find it necessary to require only a minimum number of changes to reflect specific technical effects. Section 5 lists the general guidelines followed for determining the limits for each element; the limits established in this guide are based on these guidelines. Not included in this standard stainless steel grade harmonization effort is an attempt to unify stainless steel compositions in ASTM product standards by any means other than recognizing current industry practices. 1.1 This document provides a guide to ASTM Subcommittees A01.06, A01.10, A01.17, A01.22, and A01.28 for specifying chemical composition limits of wrought stainless steels. It is intended that these recommended grade composition limits be suitable for adoption by other standardization bodies that prepare standards for stainless steel products. 1.2 Included in this guide are the recommendations for determining the number of significant figures for specifying chemical composition from Test Methods, Practices, and Terminology A 751. 1.3 All stainless steel UNS numbers and the stainless steel grades in all standards overseen by the aforementioned ASTM subcommittees have been included, except those grades applicable to restricted special end uses and alloys containing less than 10.5 % minimum chromium. 1.4 Not addressed are minor composition modifications which a specific product subcommittee may find necessary to accommodate effects of normal processing or to enhance fabricability by the producer or user, or both. 1.5 Also not generally addressed (except when established by ASTM product subcommittees) is a complete rationalization of all limits, especially when such would conflict with long-standing practices and is not justified by special technical effect. 1.6 Excluded from this guide are cast material and welding filler metal.
