Formerly under the jurisdiction of Committee B02 on Nonferrous Metals and Alloys, this specification was withdrawn in May 2015. This standard is being withdrawn without replacement due to its limited use by industry. The alloy is no longer in production.

This specification discusses cover plate, sheet, and strip of low-carbon nickel-chromium-molybdenum-gadolinium alloy for use for neutron adsorption, structural, and corrosive application in nuclear waste disposal service. The specimen must be composed of the following elements: molybdenum, chromium, iron, cobalt, carbon, silicon, manganese, phosphorus, sulfur, nickel, oxygen, nitrogen, and gadolinium. Each plate, sheet, or strip shall be marked on one face with the specification number, alloy, heat number, manufacturers identification, and size. The markings shall have no deleterious effect on the material or its performance and shall be sufficiently stable to withstand normal handling. Each bundle or shipping container shall be marked with the name of the material; this specification number, alloy; the size; gross, tare, and net weight; consignor and consignee address; contract or order number, and such other information as may be defined in the contract or order.

1.1 This specification covers plate, sheet, and strip of low-carbon nickel-chromium-molybdenum-gadolinium alloy (UNS N06464) as shown in Table 1, for use for neutron adsorption, structural, and corrosive application in nuclear waste disposal service.

1.2 The following products are covered under this specification:

1.2.1 Sheet and Strip—Hot or cold rolled, solution annealed, and descaled unless solution anneal is performed in an atmosphere yielding a bright finish.

1.2.2 Plate—Hot or cold rolled, solution annealed, and descaled.

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 Material Safety Data Sheet (MSDS) for this product/material, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
