Surface Status and Properties of Double Cold-reduced Tinplates

The development history of the double reduced (DR) tinplate is introduced briefly. The application, manufacturing process and surface status of the DR are reviewed. The properties of the double reduced tinplatr steel were studied by means of metallurgical microscopy, roughness testing and electrochemical methods. The results show that compared to the tinplate (MR), the corrosion resistance of the double reduced tinplate is better.
