Hot rolled and cold rolled steel are both important raw materials in the production of many types of finished steel products. So what are hot rolled vs cold rolled steel? What is the difference between these two types of rolled steel and what are the applications of these two types of rolled steel?Let's explore more deeply with MRS Steel about the basic knowledge of hot rolled & cold rolled steel as well as the benefits it brings to businesses in many different fields through the article content below.Let's learn more about hot rolled steel and cold rolled steelLearn about hot rolled and cold rolled steelHot rolled and cold rolled steel are important raw materials in the steel production process. Both types of steel are metals whose production requires high technical skills and solid expertise. Next, let's learn about hot rolled steel vs cold rolled steel.What is hot rolled steel?Hot rolled steel is a type of steel produced through a hot rolling process at high temperatures, often exceeding 1000°C. This process can change the material and shape of the metal. Hot rolled steel products are often dark green, less shiny and lack aesthetics.Hot rolled steel are usually produced at high temperaturesWhat is cold rolled steel?Cold rolled steel is essentially a hot rolled steel that has been cooled and re-rolled at room temperature. After going through the process of gradually reducing the length of the cold rolled steel, it has appropriate dimensions and smooth surface quality. Because it goes through many processing processes, cold rolled steel often has a higher price than hot rolled steel, so product quality as well as aesthetics are also highly appreciated compared to hot rolled steel.Cold rolled steel has a smoother surface than hot rolled steelDifference between Hot-rolled and Cold-rolled steelTo distinguish between hot rolled and cold rolled steel, in addition to learning about the nature through the definition of each type of steel coil mentioned above, we need to differentiate through factors such as the normal thickness, price of each type, surface, and edge of the steel coil. In addition, we can consider additional factors such as tolerance, accuracy, and storage method of each type of steel coil. Let's see the differences between these two types of rolled steel through the table below.Table comparing the differences between hot rolled steel and cold rolled steelComparison criteriaHot-rolled steelCold-rolled steel Thickness>0,9 mm0,15mm - 2,0mmSurface, colorThe surface is rough, the blue-gray color turns rusty red after a long timeSmooth surface, light gray colorEdgeThe two edges of the roll are often rounded, rough, and turn rusty when left for a long timeUsually neatly trimmedTolerance The tolerance is larger due to the production process; the hot temperature cools down, so the steel deforms itself and cannot be controlledTolerances are tighter due to reduced temperatures throughout the process and strict control of the coolant actionPrice Cheaper than cold rolled steelHigher than hot rolled steelPreservationHot-rolled steel coils can be left outdoors for long periods of time without using coveringsShould be stored indoors and should be covered with a cover to prevent scratches on the steel surface.Advantages and disadvantages of hot rolled and cold rolled steelEach type of steel will have its own advantages and disadvantages.

Carbon steel vs galvanized steel both have differences, but they can easily confuse buyers. With the naked eye, it is difficult for users to distinguish between these two types of steel.So, what is the difference between carbon steel and galvanized steel and how to distinguish them? The article below with MRS Steel compares the properties of these two popular types of steel to find their differences.What is different carbon steel vs galvanized steel? Find out with MRS SteelDefinition of carbon steel vs galvanized steelBefore learning the difference between carbon steel vs galvanized steel, we invite you to join MRS Steel to learn about the definitions of carbon steel and galvanized steel.What is Carbon steel?Carbon steel is an alloy of iron, carbon, and a few other alloying elements. The higher the carbon ratio in the alloy, the harder and harder it is to bend the steel, whereas the lower the carbon ratio, the softer and more malleable the steel. Currently, carbon steel is classified into low-carbon steel, medium-carbon steel, and high-carbon steel.Carbon steel is an alloy of iron, carbon, and a few other alloying elementsWhat is Galvanized steel? Galvanized steel is a steel material covered with an outer layer of zinc plating. This zinc coating helps steel avoid the effects of the surrounding environment. Thereby limiting the possibility of rust, oxidation, and corrosion, increasing the durability and longevity of the product. Popular types of galvanized steel today include galvanized steel pipes, galvanized steel coils, galvanized hollow sections,...We have helped you learn about the definitions of the above two types of steel. Below, let's learn about the differences between carbon steel vs galvanized steel.Galvanized steel pipesCompare carbon steel vs galvanized steelThere are some basic differences between carbon steel vs galvanized steel.Differences in product surfaceThe first difference between carbon steel vs galvanized steel is in product surface. In particular, for carbon steel pipe products, the surface will often not be treated or will be covered with a layer of grease. Galvanized products will usually be covered with a layer of zinc on the product surface. Besides galvanized steel being more durable, it also brings high aesthetics to the project in harsh weather conditions. This zinc layer has different thicknesses depending on the intended use of the steel.Manufacturing processThe second difference between carbon steel vs galvanized steel is in the production process. Typically, carbon steel is produced by adding carbon along with iron in a furnace. Carbon combines with iron to form carbon steel. Particularly for galvanized steel produced by coating the steel surface with a layer of zinc plating, there are three zinc coating methods: hot-dip galvanizing, spray galvanizing, and electrolytic galvanizing.Galvanized steel is coated by the hot-dip methodCorrosion resistanceIn terms of corrosion resistance between carbon steel vs galvanized steel, galvanized steel has more corrosion resistance.Normally, carbon steel will not have an outer coating, so it is easily oxidized, and the product surface is susceptible to rust and corrosion. From there, the product's lifespan can easily be reduced if not stored properly.Galvanized steel is covered by a layer of zinc, which helps the steel avoid environmental impacts. Besides, the plating layer also makes the product highly aesthetic, prevents oxidation, and increases the product's corrosion resistance.Product pricesComparing carbon steel vs galvanized steel, galvanized steel often has a higher cost because it is covered by a layer of plating that is much more resistant to rust, corrosion, and oxidation than carbon steel.However, if your project is not in an area subject to many environmental impacts, you can consider using carbon steel to save costs.Application of carbon steel vs galvanized steelDifferent characteristics will also create different applications to suit each product's intended use.In fact, galvanized steel is used to produce many products, such as ventilation pipes, deck floors, purlins, steel pipes, galvanized hollow sections,... to serve the fields of construction, engineering,...Carbon steel possesses many outstanding advantages, so it has become a material widely used in many different industrial fields, such as construction, the automobile industry, shipbuilding, manufacturing, bolts and screws,...Galvanized steel is used to make deck floorsMRS Steel - The Best Steel SupplierMRS Steel is one of the leading reliable addresses in the field of supplying all types of steel in the Vietnamese market.
