There are dozens of different styles and variations of steel sheets. One of the most common ways to classify them is by the temperature at which they were rolled &#; cold rolled or hot rolled. Let&#;s look at the pros and cons of cold rolled steel for your next project.
What is It?
When steel is rolled out to form a coil during its production, this is done at varying degrees of temperature. In all cases where this temperature is considered at or below the room temperature, this is considered cold rolled steel.
Cold rolled steel will be smooth to the touch, strong and not particularly flexible. It&#;s generally found in flat, square or round shapes.
Pros
There are a couple distinct benefits to cold rolled steel:
Cons
There are also a couple downsides to cold rolled steel for some people:

When you need to order cold rolled or hot rolled steel for your next fabrication project, it&#;s important to buy the right kind to match the job. Not only are there four major types or groups of steel (carbon, alloy, stainless, and tool steel), the World Steel Association has identified over 3,500 different grades of steel, each with unique characteristics and properties.
While most of the differences between steel grades have to do with their compositions&#;what percentages of carbon and other alloying materials are in the mix&#;how the steel is processed also contributes to the distinctiveness of a particular grade. One very common processing technique is rolling, which involves passing the steel through pairs of rolls at high pressure. This procedure can impart specific mechanical properties to the resulting steel stock along with making it uniform in thickness. It is estimated that nearly 90% of produced steel goes through the rolling process.
Rolling is divided into two general categories&#;cold rolling and hot rolling. All steel is created with heat, of course, and then allowed to cool. Cold rolled steel is generally processed around room temperature, while hot rolled steel is heated above the material&#;s recrystallization temperature before processing. The atoms of metals are nearly always arranged in a crystalline lattice structure. That structure gets deformed through physical processing, which can strengthen the metal, since the rearranged atoms can&#;t move as freely. When a metal reaches its recrystallization temperature&#;around one-third to one-half of its melting point&#;the atoms become more mobile and then reorient themselves into the original crystalline pattern of the material.
The two types of rolled steel can be readily distinguished from each other. Cold rolled steel has a smooth surface with an oily finish and appears dark gray, while hot rolled steel has a non-oily surface with a somewhat rough and scaly finish and a blue-gray appearance. They can also be differentiated by an examination of the edges of bar stock that is square or rectangular, since cold rolled steel will have sharp edges and hot rolled steel will have rounded ones.

It is important to understand the benefits and drawbacks of cold and hot rolled steel to properly gauge which material is better for specific projects.
Hot rolling is a common method of &#;hot working&#; a metal, which can also include other processes that are performed above the recrystallization temperature, such as drawing, extrusion, and forging. Working steel while it is hot enough to recrystallize keeps it from strain hardening, giving it different properties than cold rolled steel.
Some of the advantages of hot rolled over cold rolled steel include:
Disadvantages of hot rolled steel:
Applications that use hot rolled steel include:
When close tolerances and exact shapes aren&#;t needed, hot rolled steel is ideal for the project.
Processing steel through the cold working method of cold rolling puts the metal under mechanical stress, imparting a change to its crystalline structure.
Some of the advantages of cold rolled over hot rolled steel include:
Disadvantages of cold rolled steel:
Applications that use cold rolled steel include:
When closer tolerances and better surface finishes are needed, cold rolled steel is ideal for the job.
While cold rolled steel might generally be regarded as &#;better&#; than hot rolled steel, the key consideration is the end goal of the fabrication project. Savings in cost and ease of working must be weighed against the strength and precision required of the finished part.
A fabrication shop should establish a good relationship with a reputable steel service center or other metal supplier who can advise them on the best material for any given job, while providing fast delivery and a fair price. Likewise, having a connection with a trusted and qualified machinery consultant can assist a fabricator in finding the right equipment to complete any metalworking endeavor.
