Chromium is a metal used to induce hardness, toughness, and chemical resistance in steel.
The alloy produced is known as “stainless steel.” When alloyed with iron and nickel,
it produces an alloy known as “nichrome” which is resistant to high temperatures and used
to make heating units, ovens, and other appliances. Thin coatings of chromium alloys are
used as platings on auto parts, appliances, and other products. These are given the name
“chrome plated.” It is also used to make superalloys that can perform well in the hot,
corrosive, and high-stress environment of jet engines.
