Molybdenum containing grades of stainless steels are generally more corrosion resistant than molybdenum-free grades. They are used in applications that are more corrosive, such as chemical processing plants or in marine applications. There are many grades of stainless steels with different molybdenum (and chromium, nickel, nitrogen, etc.) contents.

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of ...

Here we outline six advantages of tungsten metal, which help to explain why it is used so widely. 1. Resistance to high temperatures. Of all metals in their purest form, tungsten has the highest melting point (3422°C). This can be hugely beneficial in certain situations (particularly when compared to other more common metals).

Although molybdenum was discovered in the late 18th century, it was used early before its discovery. For example, in the 14th century, Japan used a molybdenum-containing steel to make a saber. In the 16th century, molybdenite was used as graphite because it was similar to the appearance and properties of lead, galena, and graphite.
