Cold Rolled Steel Square Tube

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel.

Cold rolled steel square tube.

Two methods of rolling determine the steel tubing s overall strength as well as it s desirability for certain projects cold rolling and hot rolling. Cold rolled steel tubing this steel tubing begins as hot rolled steel but is processed even further to create a more finished surface and provide additional strength. The term cold rolling describes the process quite well. 1018 steel is the most common type of steel used when making cold rolled steel.

It can also be used for shafts machinery parts bolts pinions gears as well as in the creation of furniture appliances and other consumer goods. Our available stock sizes. As an example a hot rolled steel product may have a yield strength of 235 mpa. Used in general fabrication where strength is a requirement.

Steel pipe square tubing round tubing rectangular tubing rebar round bar square bar tube pipe hot rolled coil cold rolled coil galvanised coil cold formed section lipped channels. Advantages of using hot rolled steel tubes since there is less processing involved with hot rolled square steel tubing it is usually less expensive than cold rolled steel tubing. Steel stock passes through a series of rollers to be flattened out and reshaped as steel tubing. Cold rolled steel square tube is cold rolled steel that has been formed into a square tube.

Cold rolling increases the strength and hardness and decreases ductility of steel by rolling it at ambient temperature or below its recrystallization temperature. In addition to improvement of mechanical properties the cold rolling produces steel plate sheet of the desired physical dimensions. Hot rolled steel is also more malleable making it easier to bend and form the tubes into your desired shape. It is commonly referred to as hss meaning hollow structural section.

It is commonly used for parts requiring cold forming such as crimping swaging or bending. The rolls induce plastic deformation. This process is more suited for applications that have strict tolerance straightness and surface condition requirements because cold rolling is a more precise finishing method. Cold roll steel round tube tubing 143 products we carry cold roll steel round tubing in a513 and 1018 metric.

Sort by displaying 1 25 of 143 results. It is measured by taking the outer walls which are the same size and then the wall thickness. We stand to remain the premium steel supplier in south africa and ensure that we remain the top steel merchant in south africa. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa.

It contains all the typical traits of steel strength some ductility and comparative ease of machining but the process of cold rolling gives is a smooth finish and better properties than those of hot rolled steel.
