Cold rolled steel plate 100 * 200 * 0.8 rounded corners, experimental special Cold rolled steel plate

I want to confirm the difference between tinplate and cold rolled steel?

Tinplate and cold-rolled steel are two different metal materials. Tinplate has a higher carbon content than cold-rolled steel and has higher Hardness, strength and corrosion resistance. It is mainly used in high-end fields such as electronic equipment and aerospace. Cold-rolled steel has low carbon content and a wide range of applications. It is mainly used in the manufacture of automobiles, furniture, building materials and other fields. Choose according to the standard of the product you test as much as possible in the experiment.
