Material Chromium
Chromium is used in chromium plating for decoration and corrosion as well as wear protection. It is also used as an alloying element in stainless steel.

The most common form of chromium is very hard and brittle up to 700 C, and only over this temperature becomes ductile. Pure chromium is ductile, but is only produced in laboratory scale.

Chromium is resistant to corrosion and oxidation up to 1100 C, due to an resistant film that develops on the surface of the metal. These properties are transferred to alloys which contains chromium in sufficient amounts.
