PT Krakatau Nippon Steel Sumikin (KNSS) manufactures a wide range of Cold-Rolled Steel coils (CRS) in accordance with the Japanese Industrial Standards (JIS), The Japan Iron and Steel Federation Standard (JFS) and any other standard.
Cold-Rolled Steel Coils are produced by an annealing process of Cold-Rolled Full Hard Steel Coils. Cold-Rolled Full Hard Steel Coils are supplied by Nippon Steel & Sumitomo Metal Corporation and PT Krakatau Steel. Cold-Rolled Full Hard Steel coils are produced from the rolling process of Hot-Rolled Steel Coils in Cold Rolling Mill. Cold-Rolled Full Hard Steel Coils have inferior properties such as low ductility and less formability. By annealing process, we produce Cold-Rolled Steel Coils with improved ductility and formability.
PT Krakatau Nippon Steel Sumikin manufactures Cold-Rolled Steel Coil for automotive application. Cold-Rolled Steel Coils are extensively used as basic materials in various part of automobiles and motorcycles.
