Standard Specification for Ni-Fe-Cr-Mo-Cu-N Low-Carbon Alloy and Cr-Ni-Fe-N <brk/>Low-Carbon Alloy Bar and Wire, Ni-Cr-Fe-Mo-N Alloy Wire, and Ni-Fe-Cr-Mo-N Alloy Bar — 6 стр.
Реферат

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.

Область применения

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. 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.
