Chemical Properties

Chemically Balanced

Molybdenum is a key alloying agent that increases the strength and resistance to corrosion of many quenched and tempered steels, especially at elevated temperatures. Additionally, the material is added to improve the performance of some heat and corrosion resistant nickel alloys. Moly has a wide variety of applications, including but certainly not limited to boiler plates, industrial tools, gun barrels, armor plate, vacuum furnaces, light bulbs, nuclear energy, missile, aircraft parts, and many more. In fact, most high strength steels consist of between 0.25% and 8% molybdenum. While the pure material is prized for its attributes, moly alloys such as lanthanated molybdenum (MoLa), molybdenum disulfide (MoS2), and titanium zirconium molybdenum (TZM) are also useful since they expand upon the core properties while widening the range of consumer and industrial applications.
