    1.Difference Between Hot Rolled Steel and Cold Rolled Steel


    Customers often ask us about the differences between hot rolled steel and cold rolled steel. There are some fundamental differences between these two types of metal. The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by annealing and/or tempers rolling.

    Hot Rolled Steel

    Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to cold rolled.

    Uses: Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and I-beams, for example. Hot rolled steel is used in situations where precise shapes and tolerances are not required.

    Cold Rolled Steel

    Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products, when actually the product name refers to the rolling of flat rolled sheet and coil products.

    When referring to bar products, the term used is “cold finishing”, which usually consists of cold drawing and/or turning, grinding and polishing. This process results in higher yield points and has four main advantages:

    • Cold drawing increases the yield and tensile strengths, often eliminating further costly thermal treatments.
    • Turning gets rid of surface imperfections.
    • Grinding narrows the original size tolerance range.
    • Polishing improves surface finish.

    All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to hot rolled.

    Cold finished bars are typically harder to work with than hot rolled due to the increased carbon content. However, this cannot be said about cold rolled sheet and hot rolled sheet. With these two products, the cold rolled product has low carbon content and it is typically annealed, making it softer than hot rolled sheet.

    Uses: Any project where tolerances, surface condition, concentricity, and straightness are the major factors.


    2.ERW (Electric Resistance Welded)


    The nomenclature ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (square or rectangular) shape. The edges are forced together under pressure as a butt joint and then welded by heating the material to temperatures above 2000° F. The flash weld that has formed is now removed from the outside diameter of the tube. Once the weld has been tested the tube then passes through a series of sizing rolls to attain its precise finished size, after which the tube is then straightened and cut to length.

    The material used in the manufacturing process is typically SAE 1010. This product is typically available in Cold Rolled steel (CREW) for 0.060” wall and lighter and Hot Rolled steel (HREW) for 0.083” wall and heavier. The product will come in an “as-welded” condition, (often called – flash-in condition) referring to when the flash from the weld is left on the inside of the tubing, it is not normally removed or controlled during the ERW tube production process.

    (DOM) Drawn Over Mandrel

    Technically, DOM is not a type of steel tube, but rather the process in which the tube is finished. It is considered a high quality tube, and is normally constructed from SAE 1020 or 1026 steel. The first stages of manufacturing are identical to ones used to make electric resistance welded tube, but in the finishing stages the entire flash weld is removed and the tube is cold drawn over a mandrel. The cold drawn process provides the tube with better dimensional tolerances, improved surface finish and the strongest weld strength achievable. DOM is often incorrectly referenced as “seamless tube” when it actually does have a seam (although it is almost invisible).

    Seamless Mechanical Tubing

    The seamless tube is manufactured using a process called “extrusion”. During this process a solid steel bar is pierced though the centre using a die, turning the solid round into a round tube.

    Basically there are two types of seamless tube:

    • Cold Drawn Seamless (CDS) normally made from SAE 1018, having precise tolerances and good surface finish
    • Hot Finished Seamless (HFS) normally made from SAE 1026, having less critical tolerances and a scaly finish – Not as strong as CDS

    Benefits of Cold Drawn Seamless (CDS):

    Good surface finish – Superior machinability – Increased dimensional tolerances – High strength to weight ratio

    Benefits of Hot Finish Seamless (HFS):

    Cost effective material – Good Machinability – Wide range of sizes
