(Specification)Standard Specification for UNS N08020, UNS N08024, and UNS N08026 Nickel Alloy Bar and Wire
Standard Specification for UNS N08020, UNS N08024, and UNS N08026 Nickel Alloy Bar and Wire
ABSTRACT
This specification covers UNS N08020, UNS N08026, and UNS N08024 nickel alloy bar and wire. The alloys shall be furnished in the stabilized-annealed condition, solution-annealed condition, or annealed condition. The material shall conform to the requirements as to chemical composition prescribed. The material shall conform to the applicable requirements as to mechanical properties prescribed. Chemical analysis and tension test shall be made to conform to the requirements specified.
SCOPE
1.1 This specification2 covers UNS N08020, UNS N08026, and UNS N08024 bar and wire other than required for reforging.
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.
