(Specification)Standard Specification for Nickel-Chromium-Molybdenum-Cobalt-Tungsten-Iron-Silicon Alloy (UNS N06333) Bar
Standard Specification for Nickel-Chromium-Molybdenum-Cobalt-Tungsten-Iron-Silicon Alloy (UNS N06333) Bar
ABSTRACT
This specification covers the standard for hot-finished and cold-finished UNS N06333 alloy bars and flats proposed for use in heat resisting applications and general corrosive service. Materials shall conform to mechanical properties of the material such as tensile strength, yield strength, elongation, and hardness. Each specimen will be subjected to a chemical analysis, tension, Brinell hardness, and Rockwell hardness test.
SCOPE
1.1 This specification covers wrought alloy UNS N06333 in the form of hot-finished and cold-finished bars and flats 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 re mathematical conversions to SI units that are provided for information only and are not considered standard
