Cold Rolled Steel Plate

Definition - What does Cold Rolled Steel Plate mean?

A cold rolled steel plate is a volume of an iron-based alloy that is longer and wider than it is thick with approximately 2% or less carbon or any other alloying element in it. A cold rolled steel plate is formed by the cold rolling process, meaning that it is formed with rollers at a temperature that has not been elevated from normal temperatures.

Corrosionpedia explains Cold Rolled Steel Plate

Cold rolled steel plate is an iron-based alloy that can be made from one of several different chemical compositions. It can be a low carbon steel, meaning it has less than 0.3% carbon as measured by weight. It can also be a medium carbon steel; this category encompasses carbon percentages of roughly 0.3% to 1.5%. Cold rolled steels are generally not available in a high carbon content form because the increase in hardness that carbon gives to steel makes them difficult to form at room temperatures.

A cold rolled steel plate is not the same as a cold rolled steel sheet. While both are formed using the same process and are longer and wider than they are thick, they do differ in just how thick they are. With steel, anything less than about 3 mm or ⅛ inch in thickness is considered sheet, anything over that is considered plate. A cold rolled steel sheet will have many of the same mechanical and chemical properties as a cold rolled steel plate.
