ASTM B164-2019 pdf free download.Standard Specification for Nickel-Copper Alloy Rod, Bar, and Wire
1. Scope
1.1 This specification 2 covers nickel-copper alloys UNS N04400 and N04405 3 in the form of hot-worked and cold- worked rod and bar in the conditions shown in Table 1 and cold-worked wire in the conditions shown in Table 2. 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 establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.4 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.
3. Terminology
3.1 Definitions ofTerms Specific to This Standard: 3.1.1 bar, n—material of rectangular (flats), hexagonal, or square solid section up to and including 10 in. (254 mm) in width and 1 ⁄ 8 in. (3.2 mm) and over in thickness in straight lengths. 3.1.2 rod, n—material of round solid section furnished in straight lengths. 3.1.3 wire, n—a cold-worked solid product of uniform round cross section along its whole length, supplied in coiled form. N OTE 1—Hot-worked rectangular bar in widths 10 in. and under may be furnished as hot-rolled plate with sheared or cut edges in accordance with Specification B127, provided the mechanical property requirements of Specification B164 are met.
7. Dimensions and Permissible Variations
7.1 Diameter, Thickness, or Width—The permissible varia- tions 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 4, and ofhot-worked rod and bar as prescribed in Table 5. The permissible variations in diameter of cold-worked wire shall be as prescribed in Table 6. 7.2 Out-of-Round—Hot-worked rods and cold-worked rods (except “forging quality”) all sizes, in straight lengths, shall not be out-of-round by more than one half the total permissible variations in diameter shown in Table 4 and Table 5, except for hot-worked rods 1 ⁄ 2 in. (12.7 mm) in diameter and under, which may be out-of-round by the total permissible variations in diameter shown in Table 5. Wire shall not be out-of-round by more than one-half the total permissible variations shown in Table 6. 7.3 Corners—Cold-worked bars will have practically exact angles and sharp corners. 7.4 Machining Allowances for Hot-Worked Materials— When the surfaces of hot-worked products are to be machined, the allowances prescribed in Table 7 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 prescribed in Table 8. 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 9. 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 10. 7.6.2.1 In determining straightness in the standard 42-in. (1.07-m) distance between supports or, when specified, in determining straightness in lengths not in excess of those shown in Table 10, the rod shall be placed on a precision table equipped with ball-bearing rollers and a micrometer or dial indicator. The rod shall then be rotated slowly against the indicator, and the deviation from straightness in any portion of the rod between the supports shall not exceed the permissible variations prescribed in Table 10. The deviation from straight- ness (throw in one revolution) is defined as the difference between the maximum and minimum readings of the dial indicator in one complete revolution of the rod.
