Chromium VI (Cr6+) 18540-29-9.

The chemical symbol for Chromium is Cr. Chromium is a steely-grey, lustrous, hard and brittle metal[4] which takes a high polish, resists tarnishing, and has a high melting point. Chromium is a relatively abundant element in Earth’s crust; the free metal is never found in nature. Most ores consist of the mineral chromite, the ideal formula of which is FeCr 2 O 4. Chromium is unstable in oxygen, it immediately produces a thin oxide layer that is impermeable to oxygen and protects the metal below. Applications. Chromium main uses are in alloys such as stainless steel, in chrome plating and in metal ceramics.

Chromium Molybdenum is one of numerous metal alloys sold by American Elements under the trade name AE Alloys™.Generally immediately available in most volumes, AE Alloys™ are available as bar, ingot, ribbon, wire, shot, sheet, and foil.

Stainless steel production consumes most of the chromium produced annually. Chromium is also used to make heat-resisting steel. Metallic chromium dissolves in dilute hydrochloric acid forming Cr(II) and hydrogen gas, H 2.
