Standard Specification for Molybdenum and Molybdenum Alloy Plate,<brk/>Sheet, Strip, Foil, and Ribbon

ABSTRACT
This specification covers unalloyed molybdenum and molybdenum alloy plate, sheet, strip, and foil as follows: Molybdenum 360; Molybdenum 361; Molybdenum Alloy 363; Molybdenum Alloy 364; Molybdenum 365; and Molybdenum Alloy 366. The various molybdenum mill products covered by this specification shall be formed with the conventional extrusion, forging, or rolling equipment normally found in primary ferrous and nonferrous plants. The ingot metal for Molybdenum 360 and 365 and Molybdenum Alloys 363 and 366 is vacuum arc-melted in furnaces of a type suitable for reactive, refractory metals. For Molybdenum 361 and Molybdenum Alloy 364, the metal is consolidated by powder metallurgy methods. The molybdenum and molybdenum alloy ingots and billets for conversion to finished products covered by this specification shall conform to the chemical composition requirements for carbon, oxygen, nitrogen, iron, nickel, silicon, titanium, tungsten, zirconium, and molybdenum. The material shall conform to the mechanical property requirements for tensile strength, yield strength, elongation, and minimum bend radius.
SCOPE
1.1 This specification covers unalloyed molybdenum and molybdenum alloy plate, sheet, strip, foil, and ribbon as follows:  
1.1.1 Molybdenum 360—Unalloyed vacuum arc-cast molybdenum.  
1.1.2 Molybdenum 361—Unalloyed powder metallurgy molybdenum.  
1.1.3 Molybdenum Alloy 363—Vacuum arc-cast molybdenum-0.5 % titanium-0.1 % zirconium (TZM) alloy.  
1.1.4 Molybdenum Alloy 364—Powder metallurgy molybdenum-0.5 % titanium-0.1 % zirconium (TZM) alloy.  
1.1.5 Molybdenum 365—Unalloyed vacuum arc-cast molybdenum, low carbon.  
1.1.6 Molybdenum Alloy 366—Vacuum arc-cast molybdenum-30 % tungsten alloy.  
1.1.7 Drawing Grade—A drawing grade is defined, which may be specified as a separate requirement by the purchaser.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.2.1 The ball punch deformation test called for in 8.4 is a test that is specified in the inch-pound system, and original test results used to produce Fig. 2 were all obtained using inch-pound measurements. For this reason, the graph of minimum required cup height as a function of sheet thickness has been retained in its original inch-pound system. The graphical data has been scanned and a straight line fitted to the scan data. The equation of this line is included in both inch-pound and SI units.  
1.3 The following precautionary caveat pertains only to the test method portions 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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
