They are coated with Linear Low Density Polyethylene Liners which keeps the acids from making contact with the metal.
A typical bean tin is usually made of steel coated with tin. This coating helps prevent the steel from corroding and affecting the taste or quality of the beans inside the tin.
Corroding is erosion by chemical action, to keep it simple.
The element used to coat steel in food containers is usually tin. Tin provides a protective layer that helps prevent the steel from corroding and reacting with the food stored in the containers.
The answer is Aluminum (Al)
Yes, corroding metal is a chemical change because it involves a chemical reaction between the metal and substances in its environment, such as oxygen or water. This reaction causes a change in the composition and properties of the metal.

Aluminium has a natural coating of Aluminium oxide that prevents it from oxidizing (corroding). This layer forms as soon as the Aluminium is made and is impervious to oxygen and water and prevents further oxididation. Some acids and bases can dissolve this layer and then the Aluminum will corrode.
The element used to coat steel in food containers is usually tin. Tin provides a protective layer that helps prevent the steel from corroding and reacting with the food stored in the containers.
Usually you have to stop it corroding FIRST, then paint it to protect it.
Tin is a soft, malleable, and ductile metal with a silvery-white color and a relatively low melting point. It is corrosion-resistant and does not oxidize easily. Tin is commonly used in alloys, soldering materials, and as a coating to prevent other metals from corroding.
Rusting
The metal is getting rusty!
(adj.) - capable of burning or corroding by a chemical action; sarcastic, biting
to stop is from corroding!...
THERMITE
It stops the steel from rusting by not letting oxygen or water touch the steel, as oxygen and water need to present for steel to rust.
