Chromium is a hard, steel-gray, shiny, metal that breaks easily. It does not react with water but reacts with most acids.

About 70 percent of all chromium is used in the production of stainless steel. The applications of stainless steel are almost endless. They include automobile and truck bodies, plating for boats and ships, construction parts for buildings and bridges, parts for chemical and petroleum equipment, electric cables, machine parts, eating and cooking utensils, and reinforcing materials in tires and other materials.

Some chromium is used to make refractory bricks. A refractory material can withstand very high temperatures by reflecting heat. Refractory materials are used to line high-temperature ovens.

How Chromium Works

0 Comment

The melting point of chromium is the lowest of the abundant refractory metals, but it is more than 700 degrees above that of iron. The density of chromium is slightly less than that of iron. At elevated temperatures, it acquires an adherent oxide film on the surface that tends to protect it from further oxidation […]
