Stainless steel chopsticks 304 and 316 which is good
Stainless steel chopsticks 304 and 316 which is good, many things in our daily life are made of stainless steel, such as the rusty steel bowls, stainless steel cups and so on, and stainless steel chopsticks, so stainless steel chopsticks 304 and 316 which is good?
Stainless steel chopsticks 304 and 316 which is good 1
If it is used for tableware, there should not be much difference, both can, 304 is also cheaper.
However, the two stainless steel composition is somewhat different, 304, 316 are austenitic stainless steel, 316 is in 304 stainless steel inside the addition of molybdenum, so 316 stainless steel seawater rust ability than 304 to be much better. 304, 316 is the difference between the rust performance is different, 304, 316, because in addition to containing chromium, but also contains nickel, molybdenum, and therefore the performance of the rust performance is much better than 430 stainless steel. To be much better than 430 stainless steel, the price is also much higher. In addition, 304, 316 is not magnetically conductive, can not be sucked with a magnet. Generally in a high-pressure electromagnetic environment will not heat, so use more.
304- that is, 18/8 stainless steel, GB grade 0Cr18Ni9
309- compared to 304 has a better temperature resistance
316- after 304, the second most widely used steel, mainly used in the food industry and surgical equipment, mainly for The addition of molybdenum gives it a special corrosion-resistant structure, and it is also used as a "marine steel" because of its better resistance to chloride corrosion than 304, SS316 is commonly used in nuclear fuel recovery devices, and 18/10 grade stainless steel is often used in this application
The second most widely used grade after 304. p> Stainless steel 304 and 316. The Difference? The difference between stainless steel 304 and 316, 316 stainless steel in 304 based on the addition of Mo elements, so that its corrosion resistance, and high temperature strength has been greatly improved. Infants and young children with two kinds of liner as good. Water cup stainless steel is 304 good or 316 good 316 stainless steel is generally medical or make high-level tableware, corrosion resistance and heat resistance are much better than 304 stainless steel. 1, 304 stainless steel and 316 stainless steel contain Chromium are about 16~18%, but 304 stainless steel contains an average of 9% nickel, while 316 stainless steel contains an average of 12% nickel. Nickel in metal materials can improve high temperature durability, improve mechanical properties, improve oxidation resistance. Therefore, the amount of nickel in the material, it directly affects the comprehensive performance of the material. 2, 304 (0Cr18Ni9) stainless steel is austenitic stainless steel, can not be strengthened by heat treatment, can not be quenched like carbon steel, no magnetism. 304 of the various mechanical properties are relatively excellent, with considerable corrosion resistance, high temperature resistance, as stainless heat-resistant steel is most widely used. 3, 316 (0Cr17Ni12Mo2) stainless steel is after 304, the second most widely used steel, the main characteristics of acid and alkali resistance, high temperature resistance than the ability of 304, mainly used in the food industry and surgical equipment, and 316 stainless steel There is also a significant feature, that is, basically there is no thermal expansion and contraction of the phenomenon, which is extremely important for precision parts. This is extremely important for precision parts. 304 or 316 stainless steel chopsticks for home use Of course, 316 is good. But as chopsticks and not pots and kettles I feel that the difference is not big. Because chopsticks do not have to burn at high temperatures, the requirements of chemical stability is not as high as pots and pans, while the price difference is also large, if you meet the bad businessman with the price of 316 to sell you 304 things are not good to distinguish. 316 stainless steel and 304 stainless steel which is better 1, the chemical composition is different. 304 is a cover type stainless steel, its material composition is OCr18Ni9, 316L is austenitic stainless steel, material composition is OOCr12Mo2Ti. 2, different performance. 304 steel can resist sulfuric acid, phosphoric acid, formic acid, urea and other corrosion, suitable for general water, control gas, wine, milk, CIP cleaning fluid and other corrosive or non-contact material occasions. 316L steel on the basis of the increase in the molybdenum element in the 304, which can significantly improve its resistance to intergranular corrosion, oxide stress corrosion and reduce the welding of the tendency to crack the hot, and its also good resistance to chloride corrosion Performance. Commonly used in pure water, distilled water, pharmaceuticals, sauce, vinegar and other health requirements, strong corrosive medium occasions. Price 316L is 304 almost 2 times. 3, maintenance methods are different. 304 stainless steel: 18cr-8ni-0, 08c corrosion resistance, oxidation resistance and better processability, resistance to strong oxygen acid, stamping, can make containers, cutlery, metal furniture, building decoration, and medical appliances. 316 stainless steel: 18cr-12ni-2, 5Mo is more common in seaside buildings, ships, nuclear power chemical and food equipment, etc., which not only enhances the corrosion resistance to chemicals hydrochloric acid and Ocean corrosion resistance, but also enhances the corrosion resistance to brine halogen solutions. Stainless steel chopsticks 304 and 316 which is good 2 304 stainless steel is a food-grade stainless steel, more commonly used in the use of Jiatong, 316 stainless steel also added some elements, corrosion and acid resistance performance will be better, more widely used in medicine and industry, the price is more expensive, the general use of family use is not the use of 316 stainless steel. From the following three aspects of the two stainless steel From the acid and alkali resistance, 316 stainless steel is certainly better than 304 stainless steel, the acid and alkali resistance between them is different, the acid and alkali resistance of 316 is greater than 314 stainless steel. Acid and alkali resistance, the reason they both contain different composition, because the 316 element content is higher than the 314 element content, so 316 stainless steel will be better than ordinary stainless steel on the market. From the price point of view, The price of 304 is lower than the price of 316 stainless steel. 316 stainless steel because of its own composition of the content of the different, so 316 stainless steel prices have reached the 304 stainless steel price of two times. In daily life, the use of 304 stainless steel more, also because the price is lower From the use of the environment, Above said that 304 stainless steel is food grade stainless steel. It is often used in our daily life to make chopsticks, kettles, bowls and spoons and so on. Because 316 stainless steel itself is resistant to corrosion, so it is also often used in the production of medical equipment or industrial equipment. Which is the best stainless steel chopsticks, 304 or 316?3 Which is the best stainless steel chopsticks, 316 or 304? 304 Stainless Steel First of all, I would like to introduce 304 stainless steel, all stainless steel is composed of iron, a small portion of the composition of carbon, nickel, chromium. Because the composition of stainless steel is different, corrosion resistance is different, the name is naturally different. 304 stainless steel must contain 18% chromium and 8% nickel, 304 stainless steel is food-grade stainless steel, used in the home inside has been more than enough. 316 Stainless Steel I'll come back to 316 Stainless Steel below, it says that the reason why the names of stainless steel are different is because of the different stainless steel composition content. 316 stainless steel added MO element, corrosion resistance and acid resistance is better, widely used in medicine and industry, the price is more expensive, the general family will not use 316 stainless steel. From three aspects of the analysis of these two stainless steel: 1, acid and alkali resistance 316 stainless steel acid and alkali resistance than 304 stainless steel is certainly good, the main reason is that the two components of the content is different, 316 stainless steel MO element content is higher, MO corrosion resistance is very good! 2, price 304 stainless steel price is lower than 316 stainless steel, is the common people's home affordable stainless steel type. 316 stainless steel because of the different composition content, so the price of 304 stainless steel can be up to two times. 3, the use of the environment Above said 304 stainless steel is food-grade stainless steel, so it is often used to make kettles, chopsticks, rice bowls. 316 stainless steel is often used to make medical equipment or industrial equipment because of its strong corrosion resistance. How to recognize stainless steel? 1, with a special test liquid To test the authenticity of stainless steel, you can buy a bottle of stainless steel test liquid. Drop the test liquid on the surface of the stainless steel, there will be a color change, through the manual can distinguish between different colors represent which grade of stainless steel. It should be noted that if the stainless steel surface has a coating, you need to scrape off the coating before testing. 2, look at the logo nameplate You can see the first and second pictures of my article, the regular 316 and 304 stainless steel are marked with steel, if you buy stainless steel inside the steel is not steel, most likely is fake. Summary: 304 and 316 stainless steel can not say who is good and who is not good, 316 corrosion resistance is better, often used in the production of medical equipment and industrial equipment. 304 stainless steel is food grade, often used to make dishes, kettles.
