ASTM B872-06

Standard Specification for Precipitation-Hardening Nickel Alloys Plate, Sheet, and Strip

ABSTRACT
This specification covers rolled precipitation hardenable UNS N09908, N09925, and N07725 nickel-iron-chromium-columbium-titanium-aluminum alloy plates, sheets, and strips in annealed condition. These materials are used as sheathing for superconductor cables, tooling for the fabrication of such cables and for other applications that require materials with low coefficients of expansion. Precipitation heat treatments for the materials entail heating to a specified temperature, holding at that temperature and then air or furnace cooling.
SCOPE
1.1 This specification covers rolled precipitation hardenable nickel-iron-chromium-columbium (Nb)-titanium-aluminum alloy (N09908) plate, sheet, and strip in the annealed condition (temper). This alloy is used as sheathing for super conductor cables, as tooling for fabrication of such cables, and for other applications requiring a material with low coefficient-of-expansion properties.
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.
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.
