Description

Steel

Carbon is removed from molten iron by blowing oxygen into it. The oxygen reacts with the carbon, producing carbon monoxide and carbon dioxide, which escape from the molten metal. Enough oxygen is used to achieve steel with the desired carbon content. Other metals are often added, such as vanadium and chromium, to produce alloys with properties suited to specific uses.

There are many different types of steel, depending on the other elements mixed with the iron.

A summary of the properties of some different steels

Type of steelIron alloyed withPropertiesTypical use
low carbon steel about 0.25 percent carbon easily shaped car body panels
high carbon steel up to 2.5 percent carbon hard cutting tools
stainless steel chromium and nickel resistant to corrosion cutlery and sinks
