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 alloy (UNS N08825, UNS N08221, and UNS N06845)3 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 and health practices, and determine the applicability of regulatory limitations prior to use.
