(Specification)Standard Specification for Iron-Nickel-Chromium-Molybdenum Alloy (UNS N08028)* Plate, Sheet, and Strip
Standard Specification for Iron-Nickel-Chromium-Molybdenum Alloy (UNS N08028)* Plate, Sheet, and Strip
ABSTRACT
This specification covers solution-annealed UNS N08028 iron-nickel-chromium-molybdenum alloy plates, sheets, and strips. In preparing the materials, the final heat treatment should be a solution-anneal which can be followed by minor cold working such as flattening or temper rolling. The recommended solution-anneal consists of heating to a minimum temperature and rapid cooling.
SCOPE
1.1 This specification covers iron-nickel-chromium-molybdenum alloy (UNS N08028)* plate, sheet, and strip in the solution-annealed condition.
1.2 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.
1.3 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.

7. Mechanical Properties
7.1 The material shall conform to the requirements as to the mechanical property prescribed in Table 2.
8. Dimensions and Permissible Variations
8.1 Sheet—Material furnished under this specification shall conform to the applicable requirements of the current edition of
Specification B 906, B906, except as specified in TablesTable 3 and and Table 44.
8.2 Cold-Rolled Strip—Material furnished under this specification shall conform to the applicable requirements of the current
edition of Specification B 906, B906, except as specified in Tables 5-7.
8.3 Plate—Material furnished under this specification shall conform to the applicable requirements of the current edition of
Specification B 906.B906.
9. Sampling
9.1 Sampling for Chemical Analysis, Mechanical Testing, and Corrosion Testing shall be performed in accordance with
Specification B 906, B906, except as specified herein:
9.1.1 Plate—Alot of plate for testing and inspection purposes shall consist of the products resulting from the rolling of one heat
of material in the same condition and specified thickness, solution annealed by the same practice, but in no case more than 25 000
lb (11 340 kg).
9.1.2 Sheet and Strip—A lot of sheet or strip for testing and inspection purposes shall consist of material from one heat in the
same form (sheet or strip), condition, finish, and specified thickness, solution-annealed by the same practice but in no case more
than 25 000 lb (11 340 kg).
9.2 Sampling for Mechanical Tests:
9.2.1 When samples are to be taken after delivery, the purchaser of material ordered to cut lengths may request on the purchase
order additional material of adequate size to provide sample coupons for inspection purposes.
10. Number of Tests and Retests
10.1 In the case of sheet or strip supplied in coil form, two or more tension tests (one from each end of each coil), and one or
more hardness tests shall be made on specimens taken from each end of the coil. When material is supplied in flatsheet, flat strip,
or plate, one tension and one or more hardness tests shall be made on each 100 or less sheets, strips, or plates of the same lot.When
specified, one corrosion test shall be conducted for each lot.
10.2 If any specimens selected to represent any lot fail to meet any of the test requirements, the material represented by such
specimens may be retested. If there is valid reason to believe the result is not representative, the material may be re-reannealed
and retested.
11. Specimen Preparation
11.1 Tension test specimens from material under ⁄2 in. (12.7 mm) in thickness shall be of the full thickness of the material and
machined to the form and dimensions shown for the sheet-type specimen in Test Methods E 8E 8E8/E8M. Tension test specimens
