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-niobium-titanium-aluminum alloy (N09908), nickel-chromium-molybdenum-copper-titanium-niobium alloy (N09925), nickel-chromium-molybdenum-niobium-titanium alloy (N07725) and nickel-chromium-cobalt-titanium-niobium alloy (N07740) plate, sheet, and strip in the annealed condition (temper). Alloy N09908 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. Alloys N09925 and N07725 are used in sour service conditions in oil and gas applications. Alloy N07740 is used in the construction of high temperature boilers, pressure vessels, and heat exchangers.
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 Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
