1. Scope
1.1 This specification covers nickel (UNS N02200), low carbon nickel (UNS N02201), and solution strength- ened nickel (UNS N02211) in the form of hot-worked and cold-workedrodandbarintheconditions showninTable1. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 bar, n —material ofrectangular (flats), hexago- nal, or square solid section up to and including 10 in. (254 mm) in width and 1 ⁄ 8 in. (3.2 mm) andoverin thickness in straight lengths. NOTE 1 — Hot-worked rectangular bar in widths 10 in. (254 mm) and under may be furnished as hot-rolled plate with sheared or cut edges in accordance with Specification B 162, provided the mechanical property requirements of Specification B 160 are met. 3.1.2 rod, n — material of round solid section fur- nished in straight lengths.
4. Ordering Information
4.1 It is the responsibility ofthe purchaser to specify all requirements thatare necessary forthe safe andsatisfactory performance of material ordered under this specification. Examples ofsuch requirements include, but are not limited to, the following: 4.1.1 ASTM designation and year of issue. 4.1.2 UNS number. 4.1.3 Section —Rod (round) or bar (square, hexago- nal, or rectangular). 4.1.4 Dimensions — Dimensions including length. 4.1.5 Condition. 4.1.6 Finish. 4.1.7 Quantity — feet or number of pieces. 4.1.8 Certification — Certification and a report of test results are required (Section 15). 4.1.9 Samples for Product (Check) Analysis — State whether samples for product (check) analysis should be furnished. 4.1.10 Purchaser Inspection — If purchaser wishes to witness tests or inspection of material at place of manu- facture, the purchase order must so state indicating which test or inspections are to be witnessed.
5. Chemical Composition
5.1 The material shall conform to the composition lim- its specified in Table 2. 5.2 If a product (check) analysis is performed by the purchaser, the material shall be done per Specification B 880 and the material shall conform to the product(check) analysis variations defined in Check Analysis Variation table of Specification B 880.
7. Dimensions and Permissible Variations
7.1 Diameter, Thickness, or Width — The permissible variations from the specified dimensions as measured on the diameter or between parallel surfaces of cold-worked rod and bar shall be as prescribed in Table 3, and of hot- worked rod and bar as prescribed in Table 4. 7.2 Out-of-Round— Hot-worked rods and cold-worked rods (except“forging quality”), allsizes, instraightlengths, shall not be out-of-round by more than one half the total permissible variations in diameter shown in Tables 3 and 4, except for hot-worked rods 1 ⁄ 2 in. (12.7 mm) in diameter and under, which may be out-of-round by the total permis- sible variations in diameter shown in Table 4. 7.3 Corners — Cold-worked bars will have practically exact angles and sharp corners. 7.4 Machining Allowances for Hot-Worked Materi- als — When the surfaces of hot-worked products are to be machined, the allowances prescribed in Table 5 are recommended for normal machining operations. 7.5 Length — The permissible variations in length of cold-worked and hot-worked rod and bar shall be as pre- scribed in Table 6. 7.5.1 Rods and bars ordered to random or nominal lengths will be furnished with either cropped or saw-cut ends; material ordered to cut lengths will be furnished with square saw-cut or machined ends. 7.6 Straightness: 7.6.1 The permissible variations in straightness of cold-worked rod and bar as determined by the departure from straightness shall be as prescribed in Table 7. 7.6.2 The permissible variations in straightness of precision straightened cold-worked rod as determined by the departure from straightness shall be as prescribed in Table 8.
