|Chromium (Cr), molybdenunm (Mo) and tungsten (W) are rather important elements .|
|Chromium is the key ingredient for stainles steels; it is also indispensable for many other prodcuts and applications. A few million tons are produced every year; no more needs to be said.|
|Molybdenunm (Mo) and tungsten (W)
have very high metling points asn are thus indispensable for high temperature
applications (e.g. the tungsten filament in your light bulb). Both are used as
alloying element in steel (and in other alloys).
You very likely have Molybdenum silicide (MoSi2) in you household, It is usually the heating element in dishwashers or washing machines since it has the right specific resistivity and, most important, does not corrode in these extremely harsh environments.
