ASTM B688-18

Standard Specification for Chromium-Nickel-Molybdenum-Iron (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 N083672 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 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.
