18/10 stainless steel is the most used material for stainless steel pots, and has good rust resistance. Contains 10% nickel and 18% chromium.
Although it is a heavy metal, it is stable under normal conditions if better materials and manufacturing processes are selected; it will not cause any harm to health.
However, if you are in contact with salt (salt-containing food) for a long time and do not clean it promptly, hexavalent chromium will be produced, which is toxic. Better stainless steel will have no attention to maintenance.
Therefore, as long as the stainless steel cookware is cleaned in time during use and maintenance, it can be used for a long time without worry.
