410 stainless steel and 304 stainless steel belong to the same kind of stainless steel, commonly used in a variety of stainless steel products, such as dishes, chopsticks, knives and forks and other tableware, we buy tableware offline or online store, often confused about which of these two materials is better. Today, I would like to share as tableware, which one of these two materials is better?
In fact, these two materials have their own advantages and disadvantages of tableware, you should choose according to need. 304 stainless steel oxidation resistance, corrosion resistance are better, more versatile, daily dishes and pots and pans, insulation cups and so on are more suitable; 410 stainless steel has a better strength and hardness, heat conduction is also better, if you want to choose the material of knives and pots and pans, 410 stainless steel is better. better.
If you are choosing cutlery, it is recommended to prefer 304 stainless steel, because of better corrosion resistance; and in the face of such as Western-style knives and forks, due to the cutting of raw meat and other reasons, it is recommended to choose the higher hardness of 410 stainless steel material of the knife and fork. If purely from the price consideration, choose 410 stainless steel material is cheaper, but in fact, 304 material cost-effective is also very high.
From the following comparison table, you can see the difference and connection between these two materials, if the content of this table does not understand thoroughly, please continue to see the detailed comparison!
Stainless steel 304 and 410 comparison table
A, material composition and corrosion resistance
304 stainless steel contains 17%-19% chromium and 8%-10% nickel elements; while 410 stainless steel contains 0.15% carbon and 11.5%-13.5% chromium and no nickel. 304 stainless steel contains more chromium than 410, so the corrosion resistance, oxidation resistance and high temperature resistance characteristics are much stronger. For example, common foods and environments will not cause corrosion on 304 stainless steel, while 410 stainless steel is a little more prone to corrosion. This is very important for tableware, choose 304 material tableware, longer service life, and the appearance of long time use change is not easy to be corroded.

Two, strength and hardness
410 stainless steel is martensitic form, half martensitic, and 304 stainless steel is austenitic form, so 410 stainless steel is stronger and harder than 304 stainless steel. Therefore, 410 stainless steel is mostly used in the automobile transportation industry and is not afraid of collision, while 304 stainless steel is mostly used in life scenes, such as pots and pans, water cups and so on. Particularly for cutlery, 410 stainless steel is mostly used for knives and forks and other Western-style cutlery, suitable for cutting raw meat and other ingredients, while 304 stainless steel is used for Chinese dishes and chopsticks, the hardness requirements are not so high.

Three, thermal conductivity
410 stainless steel is one of the most commonly used martensitic stainless steel, and austenitic (such as AISI304 and AISI316), Martensitic has good thermal conductivity, while 304 stainless steel has poor thermal conductivity. 304 stainless steel has poor thermal conductivity. This leads to the fact that many pots and pans tend to be made of 410 stainless steel on the bottom, and less often 304 stainless steel.
Four, price and use
410 stainless steel is generally used for bolts, nuts, pump parts, cutlery, ruler, etc., for the general purpose of steel, cutting edge steel. 304 stainless steel has corrosion resistance, high temperature resistance, good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industries And the food and medical industry, and can be used to make the requirements of good overall performance of equipment and machine parts. 304 stainless steel is widely used, we commonly used pots and pans, cups and so on most of the use of this material.
When used as tableware, 410 stainless steel price is often relatively lower than the price of 304 stainless steel, because it contains more rare metals. For example, a brand of Jingdong 410 stainless steel four-piece Western set of 19.9 yuan, while the same cutlery 304 two-piece set also need 19.9 yuan, on average about half cheaper.
Five, suggestions and notes
If you are choosing cutlery, in the face of these two materials, most of the cutlery is recommended to prefer 304 stainless steel, because of better corrosion resistance; and in the face of, for example, Western-style knives and forks, due to the cutting of raw meat, etc., it is recommended that you choose the hardness of the 410 stainless steel material of the knife and fork higher If purely from price considerations, choose 410 stainless steel knife and fork with higher hardness. If purely from the price consideration, choose 410 stainless steel material is cheaper, but in fact, 304 material cost-effective is also very high.
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 tableware, which clearly specifies what kind of standard stainless steel in contact with food should meet.
