(Specification)Standard Specification for Iron-Nickel-Chromium-Molybdenum Alloys (UNS N08366 and UNS N08367) Rod, Bar, and Wire
Standard Specification for Iron-Nickel-Chromium-Molybdenum Alloys (UNS N08366 and UNS N08367) Rod, Bar, and Wire
ABSTRACT
This specification covers the standard for hot-finished and cold-finished rounds, squares, hexagons, octagons, and rectangles made from iron-nickel-chromium-molybdenum alloys (UNS N08366 and UNS N08367). Mechanical properties such as tensile strength, yield strength, and elongation shall be tested accordingly. Each specimen shall be subjected to chemical analysis and tension test.
SCOPE
1.1 This specification covers iron-nickel-chromium-molybdenum alloys (UNS N08366 and UNS N08367)* in the form of hot-finished and cold-finished rounds, squares, hexagons, octagons, and rectangles.
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.
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 12, of this specification: 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.
