what are the characteristics and properties of chromium?
316152
Chromium is a lustrous, brittle, hard metal. Its colour is silver-gray and it can be highly polished. It does not tarnish in air, when heated it borns and forms the green chromic oxide. Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below.

Chromium is used in stainless steel to provide durability as well as resistance to rust and corrosion, while nickel is used to give flatware its luster. 18/10 (304 stainless steel) - Contains 18% chromium and 10% nickel. 18/0 (420 stainless steel) - Contains 18% chromium and 0% nickel.
