Standard Specification for Nickel-Chromium-Molybdenum-Cobalt-Tungsten-Iron-Silicon Alloy (UNS N06333) Plate, Sheet, and Strip
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, sheet, and strip intended for heat resisting applications and general corrosive service.
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.
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.
