Steel, a variant of iron with carbon added, often has other elements added to it in order to prepare it for processing and industrial use. While you may have heard of tempering, not all steelmaking processes involve heating the steel to its recrystallization temperature. Cold rolling, for example, is a popular treatment process that strengthens steel into a product called Cold Rolled Steel.

Unique Properties of Cold Rolled Steel
Cold Rolled Steel, often abbreviated as CR or CRS, is known for being extremely ductile. Additionally, it is formable for moderate draw applications, as well as being non-shrinking and non-creeping at ambient temperatures.
Most often, you'll find details about Cold Rolled Steel as it compares to Hot Rolled Steel. Here are a few of the key differences between the two products:
COMMON COLD ROLLED STEEL PRODUCTS
With better surface characteristics and fewer imperfections, Cold Rolled Steel is most commonly used for precise applications where appearances are important. In addition, because of its tight size tolerance and excellent machinability, CRS is used across a wide variety of industries. Let&#;s discuss a few.
COLD ROLLED STEEL IN CONSTRUCTION
In the construction world, Cold Rolled Steel is commonly used to produce structures like beams, structures, columns, and sections. It also is frequently used in the construction of steel sheds, industrial buildings, and garages.
COLD ROLLED STEEL IN APPLIANCES AND MACHINERY
Cold Rolled Steel can be cut, bent, punched, drilled, and formed a lot easier than other metals, while also providing workable mechanical properties and low yield strength. On top of it all, the glossy and clean finish makes it the preferred choice for most mechanical production companies. This is why you can find Cold Rolled Steel in most household appliances, including washing machines, dryers, refrigerators, electric fans, and microwave ovens.
COLD ROLLED STEEL IN AUTOMOTIVE
As you can see, Cold Rolled Steel is everywhere you look! Because of its shock-proof and wear-resistant qualities, it&#;s also frequently used in the automotive industry. Electric motors, seat parts, and fuel tanks are all fabricated with CRS.

Are you in need of high-quality Cold Rolled Steel or other specialty metals?
The steel industry heavily relies on cold rolling. The cold rolling process involves passing the desired sheet of metal between rollers. (Read more about different types of rolling mills and how to choose the rolling mill machine)
Should the desired result be a sheet or harder and firmer metal, flat rolling is used. For rods or bars of metal, profile rolling is the correct method.
The beginning of the process involves hot rolling the metal, whereby the temperature of the rollers reaches 900 degrees Celcius or more.
The metal will then be processed into cold rolling, which involves letting the metal cool down to room temperature before pickling the metal. Pickling the metal involves removing the scale that is leftover from hot rolling. The scale will interfere with the process.
Thereafter, the metal is sent through rollers that are lower than the recrystallisation temperature. This helps to relieve stress from the metal. As a result, the metal will be stronger and harder.
Each cold rolling process will reduce the metal anywhere between 50 and 90 per cent. Plus, it will increase dimensional accuracy by up to 20 per cent.
