ASTM B718-22

Standard Specification for Nickel-Chromium-Molybdenum-Cobalt-Tungsten-Iron-Silicon Alloy Plate

ABSTRACT
This specification covers nickel-chromium-molybdenum-cobalt-tungsten-iron-silicon alloy (UNS N06333) plate, sheet, and strip intended for heat resisting applications and general corrosive services. Tension, Rockwell hardness, and Brinell hardness tests shall be performed on the material.
SCOPE
1.1 This specification covers wrought alloy UNS N06333 plate intended for heat resisting applications and general corrosive service.  
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.
