1. Scope
1.1 This specification covers nickel-chromium-iron- molybdenum-tungsten alloy UNS N06920 in the form ofrolled plate, sheet, and strip for general corrosion service. 1.2 The following products are covered under this specifi- cation: 1.2.1 Sheet and Strip—Hot or cold rolled, annealed and descaled unless solution-annealing is performed in an atmo- sphere yielding a bright finish; and 1.2.2 Plate—Hot 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 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 ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
5. Ordering Information
5.1 It is the responsibility of the purchaser to specify all requirements that are necessary for the safe and satisfactory performance of material ordered to this specification. Ex- amples ofsuch requirements include, but are not limited to, the following: 5.1.1 Alloy. 5.1.2 Dimensions—Thickness (in decimals of an inch), width, and length (inch or fraction of an inch). 5.1.3 Certification—State whether a report of test results is required (Specification B906). 5.1.4 Optional Requirement—Plate; state how the plate is to be cut (see 8.8.1 and Specification B906, Table A2.3). 5.1.5 Purchase Inspection—State which tests or inspections are to be witnessed (Specification B906). 5.1.6 Samples for Product (Check) Analysis—State whether samples shall be furnished (Specification B906).
6. Chemical Composition
6.1 The material shall conform to the chemical composition requirements prescribed in Table 1. 6.2 If a product (check) analysis is made by the purchaser, the material shall conform to the product (check) analysis variations in accordance with Specification B906.
8. Dimensions, Mass, and Permissible Variations
8.1 For the purposes of calculating the weight of the material covered by this specification, a density of0.303 lb/in. 3 (8.39 g/cm 3 ) shall be used. 8.2 Thickness: 8.2.1 Plate—The permissible variations in thickness ofplate shall be as prescribed in Specification B906 Table A2.1 and Table 3. 8.2.2 Sheet and Strip—The permissible variations in thick- ness of sheet and strip shall be as prescribed in Specification B906 Table A2.2. The thickness shall be measured with the micrometer spindle 3 ⁄ 8 in. (9.525 mm) or more from any edge for material 1 in. (25.4 mm) or over in width and at any place on material under 1 in. (25.4 mm) in width. 8.3 Width: 8.3.1 Plate—The permissible variations in width of rectan- gular plates shall be as prescribed in Specification B906 Table A2.3. 8.3.2 Sheet and Strip—The permissible variations in width for sheet and strip shall be as prescribed in Specification B906 Table A2.4. 8.4 Length: 8.4.1 Plate—Permissible variations in the length of rectan- gular plate shall be as prescribed in Specification B906 Table A2.3. 8.4.2 Sheet and Strip—Sheet and strip may be ordered to cut lengths, in which case a variation of 1 ⁄ 8 in. (3.175 mm) over the specified length shall be permitted, with a 0 minus tolerance. 8.5 Straightness: 8.5.1 The edgewise curvature (depth of chord) of flat sheet, strip, and plate shall not exceed the product of 0.05 in. multiplied by the length in feet (0.04 mm multiplied by the length in centimetres). 8.5.2 Straightness for coiled strip is subject to agreement between the manufacturer and the purchaser. 8.6 Squareness (Sheet)—For sheets of all thicknesses and widths of6 in. (152.4 mm) or more, the angle between adjacent sides shall be 90 60.15° ( 1 ⁄ 16 in. in 24 in. or 2.6 mm/m). 8.7 Flatness—Plate, sheet, and strip shall be commercially flat. 8.8 Edges: 8.8.1 Plates shall have sheared, abrasive cut, or plasma- torch-cut edges as specified. 8.8.2 Sheet and strip shall have sheared or slit edges.
