Cold Rolled Sheet or white iron plate is the process of making iron plate by grinding. The rolling process is carried out under the recrystallization temperature. White Iron Plate is also known, with the improvement of Black Iron Plate. Cold Rolled Sheet is a type of steel product that is produced by cold rolling, and has characteristics very different from that of 'black steel' or hot rolled steel. CRS has better surface quality and is more precise, and has good mechanical properties and excellent formability. Widely used in the ordering process because of its better formability, weldability and roughness qualities. This type of steel is also used for applications in the galvanization industry, the enamel industry, and is used as a raw material for the tin-coated food can industry. For annealed sheets, the thickness ranges from 0.20 - 3.0 mm, and the thickness is reduced to 2.0 mm. Hot Rolled Coil (HRC) or Plat (HRP) is a type of steel product that is produced by a hot rolling process. Ordinary users usually refer to this product as 'black steel' in contrast to Cold Rolled Sheet which is traditionally referred to as 'white steel'. Krakatau Steel produces ordinary carbon as well as various micro-alloy steels that can be used for general or commercial quality to special qualities such as: general steel structures, automotive frames, piles, heavy equipment components, general fabrication, general pipes & tubes, pipes & tubes for linepipes and casings, gas cylinders, weathering corrosion resistance, pressure vessels, boilers and shipbuilding. Plate sizes are 0.18 to 25 mm for thickness and widths of 600 - 2060 mm, and can be supplied as coils, plates and conditions can also be rolled or pickled and oiled (HRC-PO). Krakatau Steel has a thermomechanical heat control process and a desulphurisation process using a ladle furnace, which is essential for producing high quality hot rolled steel for special applications. Krakatau Steel manufactures coils and hot plates that are devoted to the automotive industry and require better capability, traction and better surface quality. They are used for automotive frames, wheel discs and rims, as rear, fuel tanks, oil filters, etc. Also included in this group are general drawing applications that can be used outside the automotive industry but have similar requirements, notably good weldability and drawability.
The advantages and disadvantages of White Iron Plate are:
Light and Strong. The iron body has a heavy weight, but the white iron plate has a light weight but does not reduce its strength.
Easy to customize. White iron plate is easy to form such as: bending, cutting, or welding.
The price is more expensive.
It takes longer.
