The main difference between hot rolled steel and cold rolled steel is the temperature at which they are processed. Hot rolled steel is rolled above the material’s recrystallization temperature, whereas cold rolled steel is rolled below the material’s recrystallization temperature. Beyond this quality, there are a few other distinctions between the two materials, including in […]
Harden Tempered Steel Hot rolling, the process used to make hot rolled steel, involves rolling steel at high temperatures (typically over 1700˚F). These high temperatures are above steel’s recrystallization temperature, allowing the steel to be easily shaped, formed, and made in larger sizes. As it cools, hot rolled steel tends to shrink non-uniformly, giving less […]
COLD ROLLED STEEL Cold rolled steel is essentially hot rolled steel that has been further processed by being allowed to cool at room temperature and annealed or temper rolled. Cold rolling produces steel with closer dimensional tolerances and a wider range of surface finishes than hot rolling. It is also up to 20% stronger than […]
