There is no single molybdenum steel, and a wide variety of alloys containing molybdenum are produced for specific applications. Most molybdenum alloys contain anywhere from 0.25 percent molybdenum to 8 percent molybdenum. Many nickel- and titanium-based steel alloys include molybdenum as well.
Before the 20th century, tungsten was most often used to make steel alloys. In the late 19th century, researchers began to experiment with the much lighter element molybdenum and had promising results. Throughout the first half of the 20th century, molybdenum began to replace tungsten.
During World War I, the demand for tungsten drove up prices, making alternative alloys more attractive. Molybdenum not only was cheaper, the lower weight and higher heat resistance also made the metal more versatile, with manufacturers constantly finding new applications.
Modern industries continue to take advantage of the properties of this alloy. Molybdenum steel is used to make huge structural girders for the construction industry and tiny filaments for electronic devices. Parts for furnaces and turbines, automotive parts, aircraft parts and heavy machine parts such as bearings and dies are all made from these alloys. Stainless steel containing molybdenum is used throughout the pharmaceutical, healthcare, food manufacturing, restaurant and catering industries, as well as anywhere else that hygiene is an issue and sterile surfaces are required.
