Tin free steel has been developed in Japan as an alternative to tinplate for packaging of food products and general line cans. Tin free steel is manufactured by electroplating cold-rolled steel plate with chromic acid.
Like tinplate, tin-free steel has good formability and strength but it is much cheaper than tinplate. Food cans, can ends, trays, bottle caps and closures can all be made from tin-free steel.
Disadvantages of tin-free steel
*Additional cost due to compulsory lacquering
*Limitation on packing acid products
*Not suitable for soldering end seams
*Problems in welding
