1018 Cold Rolled Steel

The term steel refers to iron whereby 0.02 to 1.7% carbon has been added. There are many different types and various alloys and applications for each type. This makes steel a popular choice for many different types of products. It is used commonly in the manufacturing of automobiles, homes, cutlery, appliances and magnetic cores just to name a few. Generally it is low cost and it is easy to finish with paint or other coatings. Steel does however, have poor corrosion resistance.

The numeric system that describes types of steel helps to determine the alloying ingredients by the first two digits of the alloy number, and the last two digits refer to the carbon content. Generally, as carbon is added, machinability and weldability decreases but strength increases.

In steel manufacturing, rolling is a forming process whereby metal materials are passed through a pair of rollers. Rolling is classified according to the temperature of the metal rolled. There are different types of rolling; the most common are hot rolling and cold rolling. Cold rolling is the process that occurs when the metal is below its recrystallization temperature. When the metal is higher than its recrystallization temperature it is referred to as hot rolling.

1018 Cold Rolled Steel is medium low carbon and has good weldability and slightly better machinability than the lower carbon steels. Available in flat bar, round bar and square bar, 1018 is often zinc coated and can be stamped for easy identification. 1018 is one of the most commonly available grades worldwide. This alloy can easily be brought to a fine finish.
