ABSTRACT
This specification establishes the requirements for four classes of machinable, high-density tungsten base metal produced by consolidating metal powder mixtures, the composition of which is mainly tungsten. This material specification may be used for bare parts or for parts that may be coated with other materials for protection against corrosion and abrasion; intended for uses such as weights or counter-balances in static or dynamic balancing, high-speed rotating inertia members, radiation shielding, hypervelocity impact, and vibration-damping applications. The chemical; physical properties, such as microstructure and machinability; mechanical properties, such as tensile strength, yield strength, elongation, and hardness; and composition requirements, such as density; are detailed.
SCOPE
1.1 This specification covers the requirements for four classes of machinable, high-density tungsten base metal produced by consolidating metal powder mixtures, the composition of which is mainly tungsten. This material specification may be used for bare parts or for parts that may be coated with other materials for protection against corrosion and abrasion.  
1.2 This specification describes physical, mechanical, and microstructural testing of a material lot based on the use of test coupons, not actual parts. Sintered properties typically vary both with part size and sampling location within a given part. Results obtained from coupon testing may therefore differ from the properties of a specific location in a larger part.  
1.3 Intended Use—Parts made from this material are intended for uses such as weights or counter-balances in static or dynamic balancing, high-speed rotating inertia members, radiation shielding, hypervelocity impact, and vibration-damping applications. In selecting the appropriate alloy for a given application, it is important to note that as the tungsten content of the alloy is increased, stiffness, radiation attenuation, and density increase with an accompanying decrease in attainable ductility.  
1.4 Special Applications—For particular applications, properties or requirements other than those specified in Sections 5, 6, and 7 of this specification may be important. These alloys may contain elements which make them weakly ferromagnetic. Where freedom from magnetic response is required, this should be specified in the purchase order. Class 4 is not available in a non-magnetic grade. For purposes of this specification, non-magnetic material is defined as material having a maximum magnetic permeability of 1.05 (see Test Method A342). Also for special applications involving large sections, methods for determining internal quality, such as mechanical testing of specimens excised from these larger sections or suitable nondestructive tests may be applied. If such part property data are required, an additional part-specific test program shall be specified in the purchase order.  
1.5 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.  
1.6 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.

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.

1.1.7 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.
