Standard Specification for Nickel-Chromium-Molybdenum-Tungsten Alloy <br> (UNS N06110) Rod and Bar

ABSTRACT
This specification covers UNS N06110 nickel-chromium-molybdenum-tungsten alloy hot-worked rods and bars and cold-worked rods. The chemical compositions and mechanical properties of the materials should conform to the requirements in this specification.
SCOPE
1.1 This specification covers nickel-chromium-molybdenum-tungsten (UNS N06110) in the form of hot-worked rod and bar and cold-worked rod in the conditions shown in Table 1.
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 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.
