Comparing the two, the advantages of stainless steel are:

1) Lightweight.

2) Beautiful.

3) Strong. Not easy to break; add cold water when the pot is hot and not easy to burst.

4) Heats up quickly and saves fire.

5) Not easy to rust.

Disadvantages:

1) It cools quickly and has poor thermal insulation.

2) The controversial disadvantage is that it is not as good as an iron pot in replenishing iron.

In my opinion, whether it is an iron pot or a stainless steel pot, the phenomenon of thinning the pot after being used for many years mainly occurs in the areas outside the bottom of the pot that are often grilled by flames. After repeated high-temperature oxidation, the layers become thinner. Peel until perforated. The inside of the pot has basically not changed much. Therefore, I disagree with the statement "use elements falling from the iron pot to replenish iron".
