Among stainless steel, 304 and 316 are the two most commonly used types of stainless steel, which are very similar in many aspects, but also have some differences. Regarding health, although stainless steel itself is considered a safe and hygienic material, different types of stainless steel may differ in specific applications.

304 stainless steel: 304 stainless steel is one of the most common and widely used stainless steel materials. It has good corrosion resistance, heat resistance, and acid resistance. 304 stainless steel is commonly used in the manufacturing of utensils, cookware, and food containers that come into contact with food. It is considered food safe because it does not release harmful substances or affect the taste of food.

316 stainless steel: 316 stainless steel has stronger corrosion resistance than 304 stainless steel. It contains 2-3% molybdenum, making it more durable under conditions such as resistance to corrosive liquids, seawater, and chlorides. 316 stainless steel is commonly used for manufacturing equipment in marine environments, chemical industry equipment, and medical equipment. In certain specific applications, 316 stainless steel may be considered a healthier choice, such as in seafood processing or medical devices.
