Stainless steel is a compound word of stainless (rust)+stainless steel (iron) made by adding chromium (Cr) and nickel (Ni) to iron (Fe) so as not to sweep rust, which is a disadvantage of the metal material. In other words, it is a rust-resistant metal and does not affect the human body, and the advantages of stainless steel products are durable, versatile, and safe and worry-free, it is the best material to use for tableware.
The disadvantages of stainless steel are that it is difficult to process, the material is expensive, the weight is heavier than aluminum, and the speed of heat conduction is slow. However, once heated, it has good heat conservation to store for a long time. To compensate for the shortcomings of such materials, the new material made by combining aluminum and stainless steel is the clad metal used by finnilo.
