Hot Rolled vs Cold Rolled Steel . Since the steel never gets hot enough to be significantly malleable, the end product is usually thicker than its hot-rolled counterpart. Hot rolled products will have a scaly grey finish and more rounded and less precise corners than cold rolled steel. The finished products would have a smooth finish with almost a shiny finish. As an example, a hot rolled steel product may have a yield strength of 235 MPa. Hot rolled steel is easier to make, to shape and form. Learn why hot rolling and cold rolling steel makes a huge difference on the type of steel that is produced, why there is such a big difference in the cost of making each, the yield and tensile strength of the steel, and other physical characteristics. This is mainly because the hot rolled steel is more malleable, hence you don’t need heavier rollers or more production cycles to form a product. See our Privacy Policy and User Agreement for details. Hot rolling is carried out at a temperature of around 1,000 degrees Centigrade using a process which prevents the steel from hardening whilst it is being worked. Since the steel never gets hot enough to be significantly malleable, the end product is usually thicker than its hot-rolled counterpart. Cold rolled steel will have higher yield strength and available in the thickness range of 0.1 mm to 4 mm. Hot-rolled steel and cold-rolled steel have different causes of residual stress, so the distribution on the section is also very different. 1. Cold-rolled steel for cold forming and deep drawing is available in a range of grades. Surface finish: Cold rolled steel also looks better than hot rolled.

Lead times are an indicator of steel demand—longer lead times mean the mills are busy and less likely to negotiate on price. Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. The rolls induce plastic deformation. The hot-rolled seamless steel pipe has a larger caliber than the cold- rolled seamless steel pipe, and the surface has obvious scale or red rust. Cold rolled steel tends to shrink after it is created and formed, adding to the metal manufacturing time. See our User Agreement and Privacy Policy.
