ASTM B425-99(2005)

Standard Specification for Ni-Fe-Cr-Mo-Cu Alloy (UNS N08825 and UNS N08221) Rod and Bar

ABSTRACT
This specification covers nickel-iron-chromiummolybdenum-copper alloy (UNS N08825 and UNS N08221) in the form of hot-finished and cold-drawn rounds, squares, hexagons, and rectangles. The material shall conform to the composition limits specified. The material shall conform to the mechanical properties specified. Chemical analysis, tension test, and rounding procedure shall be made in accordance to the specified requirements.
SCOPE
1.1 This specification covers nickel-iron-chromium-molybdenum-copper alloy (UNS N08825 and UNS N08221)* in the form of hot-finished and cold-drawn rounds, squares, hexagons, and rectangles.
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.
The following precautionary caveat pertains only to the test methods portion, Section , of this specification: This standard does not purport to address all of the safety problems, 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.
