ASTM B333 - 03(2013) 
Standard Specification for Nickel-Molybdenum Alloy Plate, Sheet, and Strip
This specification covers plate, sheet, and strip of nickel-molybdenum alloys covering UNS N10001, N10665, N10675, N10629, and N10624 for use in general corrosive service. Product analysis shall be performed on the alloy and shall conform to the chemical composition requirement in nickel, molybdenum, iron, chromium, carbon, silicon, cobalt, manganese, phosphorus, sulfur, vanadium, nickel, molybdenum, aluminum, columbium, copper, tantalum, titanium, tungsten, zirconium, and magnesium. Sheet and strip shall undergo hot or cold rolling, solution annealing, and descaling unless solution annealed in atmosphere. Plates shall undergo hot or cold rolling, solution annealing, and descaling. The material shall conform to the required tensile properties such as tensile strength, yield strength, elongation, and Rockwell hardness. Sheet and strip shall conform to the specified grain size requirement

1.2 The following products are covered under this specification:
1.2.1 Sheet and Strip—Hot or cold rolled, solution annealed, and descaled unless solution anneal is performed in an atmosphere yielding a bright finish.
1.2.2 Plate—Hot or cold rolled, solution annealed, and descaled.
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 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.
