When you think of chromium, you probably think of chromium plating, a.k.a. chrome. It has another more prevalent use, however. Chromium is a key ingredient in stainless steel. Basically, it is what makes the steel stainless. As such, chromium is an important element in the steel industry and it has been for hundreds of years.

Chromium

Stainless Steel plays a unique role in metallurgy. Stainless steels are first and foremost used for their corrosion resistance. They are created by mixing iron and carbon with chromium, and sometimes nickel and other alloys.

“Chromium is the most critical component of stainless,” says John Dobek, V.P. Commercial, Stainless Steel and Aluminum at Kloeckner Metals. “Essentially you can’t have a stainless steel without the addition of chromium.”

The addition of chromium, usually 10-20 percent, makes the resulting metal alloy highly resistant to corrosion. The degree of corrosion resistance required is one factor that decides the overall required composition of the stainless steel. Malleability, temperature resistance, and aesthetics are other factors.
