Processing | The whole process is done at high temperature and at the end is being cooled down | Cold rolled steel is heated and cooled at the room temperature and then rolled after again |
Advantage | - Easier to make: heat it up, push through, cool down and that's it! - Cheaper than cold rolled - Hot rolled steel is allowed to cool at room temperature and it's free from internal stresses that can arise from quenching or work-hardening processes - Most popular shapes are hot-rolled (UC, UB, SHS, RHS, PFC, flats etc.) | - accurate shape (consistent and straight) - a wider range of surface finishes - a smooth and shinier surface - bars are true and square and have well-defined edges and corners - Tubes have better concentric uniformity and straightness. |
Disadvantage | - dimensional imperfections caused by heating (expanding) and cooling down (shrink, warpage) - rough texture on a surface, need to be removed and buffed before painting - Slight distortions | - more expensive - fewer shapes available cold-rolled (sheets, box section shapes: CHS, SHS, RHS) - additional treatments can create internal stress within the material; this can cause unpredictable warping if the steel is not stress relieved prior to cutting, grinding, or welding. |
