This specification covers alloys UNS N08925, UNS N08031, UNS N08932, UNS N08926, UNS N08354, and UNS R20033 plate, sheet, and strip in the annealed temper. The alloys shall conform to the required chemical composition such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, nitrogen, and iron. The alloys shall also conform to the required mechanical properties such as tensile strength, yield strength, elongation, and Rockwell hardness.1.1 This specification covers nickel-iron-chromium-molybdenum-copper-nitrogen low-carbon alloy, nickel-iron-chromium-silicon alloy, chromium-nickel-iron-nitrogen low-carbon alloy, iron-nickel-chromium-molybdenum-copper-nitrogen alloy, and nickel-iron-chromium-molybdenum-nitrogen alloy plate, sheet, and strip in the annealed temper.1.2 ASTM International has adopted definitions whereby some grades, such as UNS N08904, previously in this specification were recognized as stainless steels, because those grades have iron as the largest element by mass percent. Such grades are under the oversight of ASTM Committee A01 and its subcommittees. The products of N08904 previously covered in this specification are now covered by Specifications A240/A240M and A480/A480M.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.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.

This specification covers Ni-Fe-Cr-Mo-Cu-N low-carbon alloys (UNS N08925, UNS N08031, UNS N08354, and UNS N08926), Cr-Ni-Fe-N low-carbon alloy (UNS R20033) bar and wire, and Ni-Cr-Fe Mo-N alloy (UNS N08936) wire. The material shall be supplied in the solution-treated or in cold drawn condition as required. Heat treatment shall be waived for forging quality material. The alloys shall conform to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, nitrogen, and iron, as determined by chemical or product (check) analysis, and to the tensile requirements including tensile strength, yield strength, and elongation, as determined by tension test.1.1 This specification covers nickel-iron-chromium-molybdenum-copper-nitrogen alloy and chromium-nickel-iron-nitrogen low-carbon alloy bar and wire, nickel-chromium-iron-molybdenum-nitrogen alloy wire, and nickel-iron-chromium-molybdenum-nitrogen alloy bar.1.2 ASTM International has adopted definitions whereby some grades, such as UNS N08904,2 previously in this specification were recognized as stainless steels, because those grades have iron as the largest element by mass percent. Such grades are under the oversight of ASTM Committee A01 and its subcommittees. The products of N08904 previously covered in this specification are now covered by Specifications A479/A479M and A484/A484M.1.3 The values stated in inch-pound units are to be regarded as standard.

5.1 This procedure is suitable for manufacturing control and for verifying that the product meets specifications. It provides rapid, multi-element determinations with sufficient accuracy to assure product quality. The analytical performance data included may be used as a benchmark to determine if similar X-ray spectrometers provide equivalent precision and accuracy, or if the performance of a particular spectrometer has changed.1.1 This test method covers the analysis of nickel and cobalt based alloys by wavelength dispersive X-ray fluorescence spectrometry for determination of the following elements:Element Composition RangeAluminum 0.0X  to X.XXChromium 0.XX  to XX.XXCopper 0.0X  to XX.XXCobalt 0.XX  to XX.XXHafnium 0.0X to 0.XXIron 0.XX  to XX.XXManganese 0.XX to X.XXMolybdenum 0.0X  to XX.XXNickel XX.XX  to XX.XXNiobium 0.XX  to X.XXPhosphorus 0.00X to 0.0XXSilicon 0.0X to 0.XXTantalum 0.00X to X.XXTitanium 0.XX to X.XXTungsten 0.XX to X.XXVanadium 0.00X to 0.XX1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This method has been interlaboratory tested for the elements and quantification ranges specified in 1.1. The ranges in 1.1 indicate intervals within which results have been demonstrated to be quantitative by the interlaboratory study. It may be possible to extend this method to other elements or different composition ranges provided that a method validation study as described in Guide E2857 is performed and that the results of this study show that the method extension is meeting laboratory data quality objectives.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.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.

3.1 This practice can be used to extract carbides, borides, TCP and GCP phases, which can then be qualitatively or quantitatively analyzed by X-ray diffraction or microanalysis.23.2 Careful control of parameters is necessary for reproducible quantitative results. Within a given laboratory, such results can be obtained routinely; however, caution must be exercised when comparing quantitative results from different laboratories.33.3 Comparable qualitative results can be obtained routinely among different laboratories using this procedure.31.1 This practice covers a procedure for the isolation of carbides, borides, TCP (topologically close-packed), and GCP (geometrically close-packed) phases (Note 1) in nickel and nickel-iron base gamma prime strengthened alloys. Contamination of the extracted residue by coarse matrix (gamma) or gamma prime particles, or both, reflects the condition of the alloy rather than the techniques mentioned in this procedure.1.2 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.
