Excellent surface quality, excellent cold formability and a high degree of uniformity in the mechanical properties are characteristic of this working material. Portfolio The comprehensive steel grade program makes cold-rolled steel strip a true all-round material that can be used in applications from simple sections to complex deep-drawn parts. Mechanical Properties of Hot & Cold Rolled Steel The mechanical properties of steel often depend on their grade, or chemical makeup. For that reason, it is never safe to make assumptions about the mechanical properties of hot rolled vs cold rolled unless they are the same grade. Cold “rolled” steel is often used to describe a range of finishing processes, though technically “cold rolled” applies only to sheets that undergo compression between rollers. Steel forms that are pulled, such as bars or tubes, are “drawn,” not rolled. Cold Rolled Steel. Cascadia Metals carries a complete inventory of Cold Rolled Steel products. Cold Rolled Steel is essentially hot rolled steel that has been processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or temper rolling.
