This specification deals with the standard requirements for nickel-chromium-iron-molybdenum-copper alloys (UNS N06007, N06975, N06985, and N06030) in the form of plate, sheet, and strip for use in general corrosive services. These materials shall undergo hot or cold rolling, solution annealing, and descaling. The plates shall have sheared or cut machined, abrasive cut, powder cut, or inert arc cut edges while the sheet and strip shall have sheared or slit edges. Heat and product analysis shall be performed to determine the chemical composition of the specimens which shall conform to the specified nickel, chromium, iron, molybdenum, copper, manganese, cobalt, carbon, tungsten, silicon, phosphorus, sulfur, columbium, tantalum, and titanium limits. The materials shall also conform to the mechanical property requirements for tensile strength, yield strength, elongation, and Rockwell hardness.

1.1 The specification² covers plate, sheet, and strip of nickel-chromium-iron-molybdenum-copper alloys (UNS N06007, N06975, N06985, and N06030)* as shown in Table 1, for use in general corrosive 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 as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.
