What Is The Cold Rolled Steel?

Cold rolling is a fabrication process to fabricate large sheet metal which later is delivered to the metal fabricator you would hire. The sheet metal forming process is done by introducing the metal between rollers which will squeeze and compress the metal into the desired sheet metal size and thickness. This process is done by temperature which is about room temperature to gain and to increase the strength and hardness of the steel. The process follows as mentioned:

At room temperature, a steel sheet is passed through two or more rollers. The rollers decrease the thickness of the steel sheet and increase the strength and hardness. The main important thing is the sheet does not lose its ductility. This means that the end product is not prone to cracking or forming. This is the main difference to hot rolled steel.

Cold Rolled Steel Properties:

One of the most important properties is the high strength. The cold-rolling process increases the strength of the steel by 20%. It is preferred in mechanical applications as it is highly resistant to denting.

Furthermore, it also has high formability which makes it ideal even if you need to bend the steel sheet to a certain shape such as a bracket, u-channel, or z-channel. Also, it has excellent magnetic properties too. It makes it a preferred alloy for a wide range of industrial and domestic applications.

Enameling and color-coding cold rolled steel is possible. In fact, it is recommended as steel will corrode over time. By putting a protective layer of paint coating on it, the life of the metal will be increased to a great extent.

ASTM A Carbon Steel:

One of the most favored cold-rolled steel grades is ASTM A Carbon Steel which is widely used in industrial as well as domestic applications. It is a low-carbon and high-strength steel-alloy sheet metal with excellent formability. It also has superior surface texture and flatness. It can be used in exposed applications as it has a matte finish surface. To prevent rust you can oil the surface or but paint on it.

Main Applications:

Home And Office:

As it offers excellent strength and hardness, it is widely used as a bracket or angle for making home and office furniture, because cold-rolled steel can keep precise shapes and tolerances better than hot-rolled steel.

Industrial Products:

It is used in manufacturing engineering products that require tight tolerance levels and coated surfaces. Some of the examples are home appliances like ovens, washers, refrigerators, dryers, and so on. Also, it is used in the aircraft and automobile industry.

Other Applications:

It is also used in making stamped parts, shelving, and signs.

FAQ

1. Hot Rolled Steel vs Cold Rolled Steel 

Hot rolled steel vs cold rolled steel: A hot rolled steel generally involves rolling the steel at high temperatures, whereas in the case of cold-rolled steel the steel is processed in cold reduction mills. In this process, the material is cooled with the help of annealing or tempers rolling. 

2. What are the benefits of cold-rolled steel?

Cold rolled steel is significantly more strong than hot rolled steel. It also has smoother and fewer surface imperfections compared to other types of rolled steel. 

3. What's better cold rolled steel or hot rolled steel?

Depending on your needs you can choose the rolled steel that suits your requirements the best. Both colds rolled steel and hot-rolled steel are great rolled steel materials that can be used for different purposes. 

4. Cold rolled steel properties

Cold rolled steel has a tensile strength of 85,000 psi and yield strength of 45,000 psi.

Conclusion:

The steel plate has many variations, like mild steel, low carbon steel, alloy steel, etc. Each type will have various applications in the industrial sector. Therefore, importers must determine their needs to choose the most accurate and suitable products.  In this section, MRS Steel will guide you with 5 tips to choose the best steel plate.

The secret to choosing the best steel plate

MRS Steel will help you choose the best steel plate through 5 criteria to evaluate the quality and suitability:

1. Durability

The product's durability is one of the most critical considerations for importers when selecting steel plates. Steel has a significant bearing capacity and is less affected by environmental factors such as temperature, humidity... representing the safety and sustainability of the works. 

Therefore, when choosing to buy steel in general and steel plates in particular, customers are especially interested in product quality and specific product characteristics. Each type variant, such as galvanized steel, stainless steel, or color-coated steel sheet... will have different specifications, properties, and durability. 

Before you place an order, you'll need to understand your project requirements to select the correct steel. If you need to know that your project is suitable for this type of steel plate, you can contact MRS Steel via Hotline at +84 28 36 22 33 58 for the most detailed advice from a team of experts.

2. Tensile 

When choosing to buy steel plates, you must pay attention to tensile strength because this is the core property of steel. Tensile strongly influences the power of a building or other manufacturing fields; it will determine the strength and bearing capacity of the final product. The selection of steel plate grades based on the correct standards and tensile will ensure the plate can withstand heavy loads without breaking.

3. Weldability

The ability to weld will help the sheet steel bond together to create a final material suitable for the properties of each different construction. If your project requires welding of steel plates, choose product variants with weldability properties with the appropriate carbon content. Although welding can reduce the strength and hardness of steel plates, it is easy to machine into cost-effective, custom sizes and shapes.

4. Ductility

Sheet ductility is the limit to which a material can be stretched or bent before breaking completely. Customers need to choose high-ductility steel plates to ensure that they can withstand heavy loads or pressures without breaking. 

Depending on the variant of the steel plate, the internal carbon composition is different, leading to the difference in flexibility in each type. The best way to test the product's flexibility is to contact the supplier or steel industry experts for detailed advice before choosing to buy.

5. Dimensions and weight

Besides the 4 mechanical properties of steel, you need to determine the size and weight of your steel plate to order the most correct and cost-optimized order. It is usually purchased in Thickness x Width x Length units with a minimum thickness of 0.” - 0.24". Charges vary in width and length, but the most common steel plate sizes are usually 8ft wide, 12ft long, or 20ft long.

Manufacturers can cut plates into various custom sizes but cannot vary the thickness. The formula for the estimated weight for a plate order is to multiply the quantity by the volume and density:

Weight = {Thickness (mm) x Width (mm) x Length (mm) x 0. kg/mm3 } x Number of sheets

Or in pounds and inches

Weight = {[Thickness (in) x Width (in) x Length (in))] x 0. in/lb3 } x Number of sheets

*Note: Steel density 0. in/lb3 ranges from 0.28-0.291 in/lb3. The above is a good weight estimation formula, but the final material weight may vary based on the situation.
