Standard Specification for Nickel-Iron-Chromium-Molybdenum-Copper Alloys Plate, Sheet, and Strip

ABSTRACT
This specification covers rolled nickel-iron-chromium-molybdenum-copper alloy (UNS N08825 and UNS N08221) plate, sheet, and strip. The material shall conform to the chemical composition requirements specified by the reference material. The material shall conform to the mechanical properties specified by the reference material.
SCOPE
1.1 This specification2 covers rolled nickel-iron-chromium-molybdenum-copper alloys (UNS N08642, UNS N06845, UNS N08221, UNS N08825, and UNS N08827) plate, sheet, and strip.  
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.
