ASTM B386-03

Standard Specification for Molybdenum and Molybdenum Alloy Plate, Sheet, Strip, and Foil

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, and foil 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 363Vacuum arc-cast molybdenum-0.5 % titanium-0.1 % zirconium (TZM) alloy.
1.1.4 Molybdenum Alloy 364Powder 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 366Vacuum 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 The values stated in inch-pound units are to be regarded as the standard.
