The Bureau of Indian Standards has granted an all India first Licence under product certification scheme for “Hot-Rolled Mild Steel Sheet and Strip in Coil Form for Cold-Reduced Tinplate and Cold-Reduced Blackplate” to JSW Steel’s Dolvi plant in Raigad. This Indian Standard IS 2385 is covered under mandatory certification as per Quality Control Orders issued by Government of India. This standard covers the requirements of Hot rolled mild steel sheets and Strips in coil form for production of Cold Reduced tinplate and cold reduced black plate. This hot rolled coil is further cold rolled and electrolytically coated with tin. It is primarily used in food industries for packaging. Tin Mill Black Plate steel is manufactured from hot rolled coils by pickling to remove the surface oxide produced during the hot rolling stage, and cold reducing through a cold mill to the desired thickness. TMBP produces a low ductility product that is usually processed further to develop desired end use characteristics. These further reprocessing steps include annealing and temper rolling for formability and surface texture, and in some cases, tension leveling for flatness. TMBP are popular for end uses such as general line cans, automotive and construction that require malleability, but not corrosion resistance.
