When we choose slitter blade, it may involves hot rolled steel and cold rolled steel. The processing way at the mill decided which steel is matched.
In general, hot rolling is a mill process which involves rolling the steel at a high temperature.(usually over 1700°F)，it can be shaped and formed easily, and even could be made in much larger size. While compare to hot rolled steel, cold rolled steel has a further processing. the steel is processed further in cold reduction mills, when the steel cools off, it will shrink slightly, so there will be less control on the size and shape of the finished product.
