If you are looking to an alternative to more traditional metals, molydenum is the way to go. Molybdenum is considered a transition metal which is the most practical alternative to more familiar traditional metals. Molydenum is similar to silicon in the sense that they both have low thermal expansion. This allows it to be commonly used in the electronics industry for things like glass sealings and semiconductor supports, and its excellent thermal conductivity and low resistivity allow it to be widely used in the furnace industry for things like radiation screens, elements and sintering trays.
Molybdenum has good corrosion resistance particularly to hydrochloric acid. Unlike tantalum, niobium, titanium and zirconium; molybdenum is not subject to hydrogen embrittlement. With all this in mind, Molybdenum is the metal of choice for Dale Engineering and its customers.
In its pure form, molybdenum is a silvery-grey metal with a Mohs hardness of 5.5, and a standard atomic weight of 95.95 g/mol. It has a melting point of 2,623 °C (4,753 °F); of the naturally occurring elements, only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points. It has one of the lowest coefficients of thermal expansion among commercially used metals.
About 86% of molybdenum produced is used in metallurgy, with the rest used in chemical applications. The estimated global use is structural steel 35%, stainless steel 25%, chemicals 14%, tool & high-speed steels 9%, cast iron 6%, molybdenum elemental metal 6%, and superalloys 5%.
Molybdenum is also valued in steel alloys for its high corrosion resistance and weldability. Molybdenum contributes corrosion resistance to type-300 stainless steels (specifically type-316) and especially so in the so-called superaustenitic stainless steels (such as alloy AL-6XN, 254SMO and 1925hMo). Molybdenum increases lattice strain, thus increasing the energy required to dissolve iron atoms from the surface.
Because of its lower density and more stable price, molybdenum is sometimes used in place of tungsten. An example is the ‘M’ series of high-speed steels such as M2, M4 and M42 as substitution for the ‘T’ steel series, which contain tungsten. Molybdenum can also be used as a flame-resistant coating for other metals. Although its melting point is 2,623 °C (4,753 °F), molybdenum rapidly oxidizes at temperatures above 760 °C (1,400 °F) making it better-suited for use in vacuum environments.
