ASTM B688-96(2004)

Standard Specification for Chromium-Nickel-Molybdenum-Iron (UNS N08366 and UNS N08367) Plate, Sheet, and Strip

ABSTRACT
This specification covers UNS N08366 and N08367 chromium-nickel-molybdenum-iron alloy plates, sheets, and strips for use in corrosive service and heat-resisting applications. The material chemical composition and mechanical properties such as the yield strength, tensile strength, elongation, and hardness should conform to the specified requirements.
SCOPE
1.1 This specification covers chromium-nickel-molybdenum-iron UNS N08366 and UNS N08367* plate, sheet, and strip for use in corrosive service and heat-resisting applications.
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.
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.
