Historical (view previous versions of standard)
This specification covers unalloyed molybdenum and molybdenum alloy bar, rod, and wire. The following materials are covered: molybdenum 360, molybdenum 361, molybdenum 363, molybdenum 364, molybdenum 365, and molybdenum 366. These materials shall be manufactured with conventional extrusion, forging, swaging, rolling, and drawing equipment. These shall materials be made by vacuum arc-melted or powder metallurgy methods. The chemical composition shall conform to the required contents of carbon, oxygen, nitrogen, iron, nickel, silicon, titanium, tungsten, zirconium, and molybdenum. Chemical analysis shall be done. Mechanical properties shall conform to the required tension properties: tensile strength, yield strength, elongation, and diamond pyramid hardness. Tension test shall also be done.
