Standard Specification for Nickel-Molybdenum-Chromium-Iron Alloys (UNS N10003, N10242) Rod
ABSTRACT
This specification covers rods of nickel-molybdenum-chromium-iron alloys with UNS Nos. N10003 and N10242 for use in general corrosive service. Specimens shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (diameter, length, out-of-roundness, weight, and straightness), mechanical (tensile and yield strengths, and elongation), and chemical composition requirements.
SCOPE
1.1 This specification2 covers nickel-molybdenum-chromium-iron alloys (UNS N10003 and UNS N10242)3 rod for use in general corrosive service.
1.2 The following products are covered under this specification:
1.2.1 Rods 5/16 to 3/4 in. (7.94 to 19.05 mm) excl in diameter, hot or cold finished, annealed, and pickled or mechanically descaled.
1.2.2 Rods 3/4 to 31/2 in. (19.05 to 88.9 mm) incl in diameter, hot or cold finished, annealed, ground, or turned.
1.3 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.
1.4 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 and health practices, and determine the applicability of regulatory limitations prior to use.
