Not all steelmaking processes involve heating steel to or above its recrystallization temperature. Cold rolling, for example, is performed at room temperature. Not surprisingly, it requires greater pressure to roll and form steel at room temperature. Because cold-rolled steel is manipulated well below the recrystallization temperature of steel, however, it offers several benefits. Below are some of the top benefits of cold-rolled steel.

Cold-rolled steel is significantly stronger than hot-rolled steel. As the rollers compress the steel at room temperature, the steel becomes stronger due to strain hardening. Just how strong is cold-rolled steel exactly? Although there are exceptions, cold-rolled steel is typically about 20% stronger than its hot-rolled counterpart.
In addition to being stronger, cold-rolled steel has an improved surface finish. It’s smoother and has fewer surface imperfections than hot-rolled steel. Not only does this improve the aesthetics of cold-rolled steel; it makes cold-rolled steel a more suitable material for certain applications, such as the construction of bridges.
Cold rolling allows for tighter tolerances than hot rolling. What does this mean exactly? In metalworking, the term “tolerance” refers to the overall thickness of metal. Cold-rolled steel is typically thinner — without sacrificing strength — than hot-rolled steel. As a result, cold rolling offers tighter tolerances than aren’t found in other steelmaking processes.
There are several different options available for creating cold-rolled steel, some of which include full-hard, half-hard, quarter-hard and skin-rolled. Of all those options, full-hard cold rolling is often preferred because it offers the tightest tolerances. When performed correctly, full-hard cold rolling can reduce the thickness of steel by up to 50%. Other cold rolling processes can also reduce the thickness of steel, but they aren’t as effective as full-hard cold rolling.
As you can see, cold-rolled steel offers several benefits, some of which include increased strength, improved surface finish, tighter tolerances and multiple options. But there are still a few disadvantages associated with cold-rolled steel. When compared to hot-rolled steel, cold-rolled steel typically costs more money to produce. For many metalworking companies, this makes hot rolling a more attractive process.
There are many steps required in metal processing in order to achieve a high-quality product. American steel processor, National Material Company (NMC), believes there can be no exception to this rule. Steel is an alloy that is a mixture of both iron and carbon and it is durable, sustainable, and highly desired by many industries. Formal specifications and different grades of steel can affect the performance and use of the metal, but there are additional techniques within the metals’ processing that can alter the strength and finish. In this article, we will focus on one technique known as cold rolling.

Engineers and designers alike must decide on the type of metal they will need to begin work on their projects. Cold rolled steel for many reasons might be the ideal metal. “Cold rolled” refers to the process the steel undergoes before becoming the final product. The temperature is not what we may consider “cold.” Instead, the entire process occurs at room temperature and involves applying great pressure to the steel. However, this does not mean cold rolled steel never experiences its recrystallization temperature. In fact, cold rolled steel endures extreme temperatures and compression rollers just like hot rolled steel. Cold rolled steel simply undergoes more processes once it has cooled down to get exact dimensions and better surface qualities. In many cases, steel may undergo processes like rolling, turning, grinding, and polishing. Each one gives the steel a unique finish.
There are many advantages of cold rolled steel, such as increased strength. (Read about Advanced High Strength Steel, or “AHSS” here.) The compression of the steel at room temperature hardens the strain, giving the metal significant strength when compared to other types of steel. That being said, the steel is not needlessly thick to create this strength. Cold rolling allows for tighter tolerances not found within other steel manufacturing. In other words, the metal will have thinner walls without sacrificing integrity.
Cold rolled steel can be found across many industries today. It is used in parts for home appliances, roof and wall systems, metal furniture, aerospace structural members, and a wide scope of applications too numerous to list. Despite the many steps within the cold rolling process, cold rolled steel has a short manufacturing time and can be delivered promptly so customers can begin work on their projects quickly.
