Sam+Chromium

CHROMIUM Chromium can be found in Siberia. It can be shined and used on vehicles. Its commonly used for semi - trucks. Chromium is added to steel to harden it and to form stainless steel, a steel alloy that contains at least 10% chromium. Other chromium-steel alloys are used to make armor plate, safes, ball bearings and cutting tools. Chromium was discovered by Louis-Nicholas Vauquelin while experimenting with a material known as Siberian red lead, also known as the mineral crocoite (PbCrO4), in 1797. He produced chromium oxide (CrO3) by mixing crocoite with hydrochloric acid (HCl). It is a blue-white metal that is hard, brittle and very corrosion resistant.
