(Specification)Standard Specification for Precipitation Hardening Nickel Alloys Bar and Wire
Standard Specification for Precipitation Hardening Nickel Alloys Bar and Wire
ABSTRACT
This specification covers UNS N07716, N07725, N07773, N07776, N09777, and N09925 nickel alloy hot or cold finished rounds, squares, hexagons, rectangles, and cold finished wires. Bars should be supplied in solution treated conditions while wires should be in both solution-treated and cold-finished conditions. The recommended solution treatment should consist of heating the material to a certain temperature followed by rapid cooling. Solution-treated materials should at least conform to the minimum room temperature mechanical properties and should be suitable for subsequent age hardening.
SCOPE
1.1 This specification covers nickel alloys UNS N07716, N07725, N07773, N07776, N09777, and N09925 in the form of hot or cold finished rounds, squares, hexagons, rectangles, and cold finished wire.
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 The following precautionary caveat pertains only to the test methods, portion, Section 13, of this specification: 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.
