Definitions for "Cold Rolled Steel"
Cold rolling is applied to lighter gauge (7 gauge or lighter) hot-rolled steel sheets or coils to reduce the thickness of the material. This process not only results in improved gauge tolerances, but also in a smooth, attractive appearance. Cold rolled steel is generally free of rust or scale and is easy to work.
Cold rolled steels are steels that are shaped by high pressure rollers at normal temperature in the steel mill. Cold rolling work hardens the material substantially. This steel can be quickly identified by the good finish of the metal bars. Due to work hardening cold rolled steel is not as machinable as hot tolled steel. A cold rolled steel can be either a mild steel or a high carbon steel.
Steel which was reduced to final thickness in the cold state by a rolling mill. Creates a smooth surface with slight skin hardness.
