Standard Specification for Iron-Nickel-Chromium-Molybdenum Alloy (UNS N08028)* Plate, Sheet, and Strip

ABSTRACT
This specification covers solution-annealed UNS N08028 iron-nickel-chromium-molybdenum alloy plates, sheets, and strips. In preparing the materials, the final heat treatment should be a solution-anneal which can be followed by minor cold working such as flattening or temper rolling. The recommended solution-anneal consists of heating to a minimum temperature and rapid cooling.
SCOPE
1.1 This specification covers iron-nickel-chromium-molybdenum alloy (UNS N08028)* plate, sheet, and strip in the solution-annealed condition.
1.2 The values stated in inch-pound units are to be regarded as the 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 Material Safety Data Sheet 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.
