Choosing the right type of material for your project is an essential aspect of engineering and construction. Being aware of the characteristics of various metals and their uses can help you save time and money. Whether you are building a house, or are involved in the design of a bridge or another construction, it is crucial to choose the right type of material. Choosing the appropriate type of steel for the task will ensure you get the highest quality product.
Cold Rolled Steel is typically thinner than hot rolled steel but it has the same strength in tensile. In addition, cold-rolled steel is less susceptible to warping when it is welded. Cold rolled steel also has a smoother finish than hot rolled steel. Cold rolled steel is also better for uses that don’t require flexing or stress. Cold rolled steel is usually employed for products that have smooth or flat surfaces, such as computer cabinets or steel drums. It is ideal for applications that require high tensile strength like shelving and fan blades.
Cold Rolled Steel is made by rolling the steel on a series of cold rollers. After the steel is rolled, it is chilled to room temperature and then a finishing process is carried out. This is done by annealing. During annealing, the grain of the steel is reorientated, causing the microstructure to harden. This process also reduces the stress on the metal and improves its strength. The process of annealing can enhance the yield strength of steel.
Some alloys are better suited for construction, while others can be used in the marine, automotive and appliances for homes. Cold rolled steel is also available in a variety of thicknesses as well as shapes. Other shapes can be cold roll if the cross-section of the steel is uniform.
Cold Rolled Steel has a greater yield strength than hot rolled steel. Cold-rolled steel has a Tensile strength that ranges from 365 to 690 MPa. However, the strength of the steel is dependent on the amount of cold work it undergoes. Cold rolled steel can be strengthened by adding alloying elements to the steel during the process. Applications for Cold Rolled Steel that require high tensile strength and does not bend or stress. It has a smoother surface that is ideal for applications that require precision components. The process of annealing can improve the hardness of cold-rolled steel and can also increase the yield strength.
Cold Rolled Steel is not able to be bent at 90 degrees. It can however be bent in reverse without breaking. However its torsional stiffness is weak. Cold-rolled steel might require several passes through rollers to achieve the desired thickness. It is not recommended for use that require bending.
The main difference between cold-rolled steel and hot rolled steel is that hot steel is rolled at higher temperatures. It is also less brittle and thinner which makes it easier to bend and form. It has a smoother surface which makes it ideal for applications that require a polished look.
