向铁、钢及其它金属中加入合金元素便可改善它们的性能,如淬火性、常温和高温下的强度、耐腐蚀性与耐研磨性等。对美国来说,自产的所有合金元素中,唯独钼获取容易,可满足需求。含钼材料是当今能量生产和输送过程中许多方面非常重要的用料,例如,用于原子能、煤气或液化气及其它动力的发生系统,用含钼钢管远距离输送燃气和燃油。 Addition of alloying elements to iron, steel and other metals improves their properties such as hardenability, strength at room and elevated temperatures, corrosion resistance and abrasion resistance. For the United States, all the alloying elements produced, the only easy access to molybdenum to meet demand. Molybdenum-containing materials are important materials in many aspects of today’s energy production and transport processes, for example, systems for the generation of atomic, gas, or liquefied gases and other power sources that transport gas and fuel over long distances using molybdenum-containing tubes.
