(Specification)Standard Specification for UNS N08020, UNS N08024, and UNS N08026 Nickel Alloy Round Weaving Wire
Standard Specification for UNS N08020, UNS N08024, and UNS N08026 Nickel Alloy Round Weaving Wire
ABSTRACT
This specification covers UNS N08020, UNS N08026, and UNS N08024 round weaving wire. The material shall undergo solution-annealing heat treatment. The wire shall be annealed or cold drawn as a final operation to produce the specified tensile strength. The material shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, columbium+tantalum, nitrogen, and iron. The chemical composition and mechanical properties of the material as enumerated in this specification shall, in case of disagreement, be determined in accordance with the referenced ASTM documents for chemical analysis and tension test.
SCOPE
1.1 This specification covers UNS N08020, UNS N08026, and UNS N08024 round weaving wire. Note 1—Weaving wire is customarily not welded. For applications involving welding in which the wire should be stabilized against loss of corrosion resistance, the purchaser should refer to Specification B473.
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.
