Limitations of tin-free steel

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
