If you choose normal stainless steel pots and pans, 304 stainless steel and 316 stainless steel two in the end which is better? I will not hesitate to give the answer: 316 stainless steel than 304 contains more of a rare metal molybdenum (Mo), better corrosion resistance, higher hardness, more expensive, stainless steel pots and pans preferred stainless steel 316 material.
First of all, if you are the choice of daily non-food-related appliances, you can directly choose 304 stainless steel, relatively more cost-effective; if you choose food utensils, such as pots, pans, chopsticks, etc., we try to pick 316 stainless steel, of course, on the life of the requirements of a little lower, the use of 304 stainless steel will not produce any harm; and if medical, instruments and other industry-specific appliances. If it is medical, instruments and other industry-specific apparatus is best to use 316 stainless steel material. Another point to note, in the selection of stainless steel food utensils, be sure to choose food-grade stainless steel, that is, with GB 4806.9-2016 logo.
Stainless steel 304 and 316 comparison table
Stainless steel is generally made of iron as the main component, and then add some carbon compounds, nickel, chromium and other metal elements made of stainless steel grade is generally the content of these rare metals. The commonly used method of evaluating stainless steel grades is the American Iron and Steel Institute's American Standard ASTM, stainless steel 304 and 316 grades are developed according to this method.
The following I first of these two stainless steel is introduced, and then focus on the comparison.
A, 304 stainless steel
304 stainless steel is the most common stainless steel in our lives, stainless steel bowls and chopsticks, stainless steel spoons, pots and pans, most of which are made of this material. This kind of stainless steel is exposed to more acid and alkali, so it has good acid and alkali resistance, and high density, good-looking polishing.

Two, 316 stainless steel
316 stainless steel composition than 304 more than a rare metal called molybdenum (Mo), which can make the 316 better than the 304 have better corrosion resistance, therefore, is generally used in the therapeutic food, machinery, heavy industry, or in high temperature environments Do parts and other industries. 316 stainless steel pots and pans to be better quality and higher price.

Three, compare
1. material composition and corrosion resistance
316 stainless steel than 304 composition of more than a rare element molybdenum (Mo), it is this element so that 316 stainless steel than 304 corrosion resistance, oxidation resistance and high temperature resistance characteristics are much stronger. For example, common food on the 304 stainless steel will not cause corrosion, but some special food, such as carbonated beverages, white vinegar, coffee, etc., 304 stainless steel on the downhill, this time to use the 316 stainless steel, this kind of molybdenum stainless steel in the corrosion resistance to be a big cut above the general stainless steel, used to hold any food will not be corroded in the antioxidant, corrosion resistance to be better.
2. Density and hardness
316 stainless steel density is 8.03g/cm^3, while the density of 304 stainless steel is 7.93g/cm^3, 316 stainless steel density is greater than 304 density, 316 pots and pans are more adapted to wear and tear of the use of harsh environments. On the other hand, stainless steel 304 plasticity is also stronger, can be more easily made into a variety of daily utensils in life.
3. Price and use
Jingdong a 316 stainless steel pan price of 219 yuan, while the same section of 304 stainless steel pan price of 109 yuan, so 316 stainless steel pots and pans to be more expensive than the 304, on average about twice as much, and some even a few times more expensive. And for its own material and price reasons, 304 stainless steel is generally only used for daily life utensils, such as pots and pans, etc., while 316 stainless steel is mostly used in the medical, mechanical and other industries, but also some food utensils.
Four, suggestions and precautions
First of all, if you are the choice of daily non-food related appliances, you can directly choose 304 stainless steel, relatively more cost-effective; if you choose food appliances, such as pots and pans, etc., we try to pick 316 stainless steel, of course, the requirements of the life a little lower, the use of 304 stainless steel will not produce any problems. The use of 304 stainless steel will not produce any harm; and if the medical, instruments and other industry-specific appliances are best to use 316 stainless steel. Another point to note, in the selection of stainless steel food utensils, be sure to choose food-grade stainless steel, that is, with the GB 4806.9-2016 logo. GB 4806.9-2016 is the national standard for stainless steel cutlery, which clearly specifies what kind of standard stainless steel in contact with food should meet, and 304 stainless steel is the lowest grade in the stainless steel that meets the standard.
