The difference between stainless steel 201 and 410: 410 is a kind of stainless steel which has good corrosion resistance and machining parts, and is suitable for general-purpose cutting tools. 201 will rust when exposed to water for a long time. Nickel-saving steel, instead of grade 301, has magnetic properties after cold working, and is used for railway vehicles. Generally, the most used material on security windows is 201. 410 is magnetic and 201 is non-magnetic. There is a big difference in material, and it should be difficult to distinguish in color. Since the price of the 200 series is cheaper than the 300 series, and the appearance is not much different, although the performance is far worse, the application in a short period of time should have an increasing trend, especially in the inland areas of the country, where there is a lack of real understanding of stainless steel, and manganese stainless steel will have a large market.


However, since manganese-based stainless steel contains high manganese, if it is used in food utensils, it will be harmful to the human body for a long time, and once the manganese element is combined with nickel, it is not easy to separate again, which is very unfavorable for the recycling of resources, so manganese-based stainless steel is not suitable. Environmentally friendly ones will exist in the long run.


Although the 400 series ferrite is not widely used at present, it has excellent processing performance. In terms of anti-rust performance, some types of stainless iron, such as 443, can reach the level of 304 in anti-rust performance. It basically does not contain nickel and the price is cheaper, so stainless iron is more environmentally friendly. Although the general consumer still holds the concept of rusting easily with magnets, it should be the mainstream of development in the long run. The composition of 201 is 17Cr-4.5Ni-6Mn-N, which is a Ni steel grade and an alternative to 301 steel. It is magnetic after cold working and is used in railway vehicles. 410, which belongs to martensitic stainless steel, is used after quenching and tempering, and its strength, plasticity and toughness are well matched. It has good corrosion resistance in weak corrosive media with a temperature not exceeding 30 °C; sufficient corrosion resistance in fresh water, steam and humid atmosphere; stable oxidation resistance below 700 °C. In order to improve the wear resistance, corrosion resistance and fatigue resistance of the parts, carbonitriding or nitriding can be carried out. In the annealed state, the plasticity is high, and it can be used for deep rolling, stamping, bending and crimping and other cold pressing forming; it has good welding and machinability, and can be polished. It is mainly used to manufacture parts that require medium strength and high toughness under the action of corrosive medium and impact load. Chemical composition of 410 stainless steel: Carbon (C): ≤ 0.15 Silicon (Si): ≤ 1.00 Manganese (Mn): ≤ 1.00 Phosphorus (P): ≤ 0.035 Sulfur (S): ≤ 0.030 Nickel (Ni): 0410 1Cr13 not including Nickel, commonly known as stainless iron, has a low price, and its anti-corrosion ability and toughness are not as good as 304, but it has the best performance as a tool.


I can tell you responsibly that the real 200 series stainless steel is a nickel-saving stainless steel, which can be sensitized by manganese and nitrogen, so it is not magnetic. Some of this American Standard was invented when resources were tight during World War II. However, developed countries such as Europe and the United States will not use this kind of stainless steel at all, including 400 ferric stainless steel. Europe and the United States are not sensitive to price and only pursue quality, so only 300 series authenticate stainless steel is used. When I attended stainless steel conferences in the US, people only talked about authenticate, duplex stainless steels and nickel-based alloys. Only countries like Japan that lack resources and countries such as India, Brazil and China vigorously develop ferric stainless steel. Among them, Japan’s FEE does the best.

As for the 200 series stainless steel, it can be said that the current Chinese market is full of counterfeit and shoddy products, which cannot meet the requirements of the American standard. The nickel content is very small, and it is only sensitized by manganese and nitrogen. Most of them are smelted by small steel mills in the south. The quality is not guaranteed and the corrosion resistance is very poor. This all originates from the 4 steel in India, which has been carried forward in our country. In addition, large steel mills will not smelt strictly according to the American standard, because the market has been messed up, the production cost according to the standard is too high, and the price is not competitive. So there are only a few big mills in production, but not really the 200 series either.


In addition, the 400 series is not stainless steel; the correct name is ferric stainless steel. Body-centered cubic lattice structure, so it is magnetic. However, the corrosion resistance is also very strong, and some grades are even higher than 304 and 316, especially the pitting corrosion resistance, and the PRE index is higher than that of authenticate stainless steel. The disadvantage is that the processing performance is relatively poor.


410 may be a ferric or a martensite stainless steel, depending on the heat treatment state and carbon content. The chromium content is generally 12%, so the corrosion resistance is poor. It is an entry-level stainless steel and is cheap, but the processing type is poor, and it is basically impossible to weld.


Nowadays, the tableware used in many households is generally made of stainless steel. In fact, there are many types of stainless steel. Some people say that they feel overwhelmed when choosing tableware, and they don’t know which stainless steel to buy. So, which is better for 201 stainless steel and 410 for tableware? Let us take a look at the problem together.


First of all, the characteristics of 201 stainless steel and 410 stainless steel are different. 410 is a kind of stainless steel, which has good corrosion resistance and inalienability; 201 stainless steel has certain acid and alkali resistance, high density, Polished without bubbles, no pinholes and other characteristics. Secondly, the uses of the two are also different. 410 stainless steel is generally used for knife blades, mechanical parts or tableware, while 210 stainless steel is used for various watch cases, watch straps and bottom covers.


Also, 410 stainless steel is magnetic, while 201 stainless steel is not. Therefore, when people choose stainless steel utensils, it is best to choose 410 stainless steel, because stainless steel of this material is more suitable for tableware, but people need to do the necessary disinfection work before use.

Bao Ma will strictly check when purchasing all the things that are in close contact with children, because some toxic substances will directly affect the baby’s health, so the tableware materials used for the baby should be safe and should not contain toxic ingredients. At present, there are many kinds of tableware on the market, and there are many kinds of materials, so is 201 stainless steel tableware safe, and is food-grade 201 stainless steel tableware safe?


Compared to food grade stainless steel 304 and 316, 201 stainless steel cutlery is not safe. 201 stainless steel is a very cheap stainless steel, which is mainly used in the manufacture of industrial pipe products and decorative pipe products. Moreover, 201 stainless steel is not a food-grade stainless steel material. It is an alloy with poor corrosion resistance. It also contains heavy metals such as nickel and chromium. It is not suitable for use in containers that come into contact with food.


Generally, the stainless steel tableware selected for children can choose food-grade 304 or 316 stainless steel. Food-grade 304 or 316 stainless steel is non-toxic. The 304 / 316 stainless steel tableware produced by regular manufacturers is harmless to the human body and can be used with confidence. However, 304 and 316 stainless steel tableware is easy to be hot, so be careful when using it.


In fact, tableware made of 201 stainless steel is not only not safe, but also some unscrupulous merchants use 201 stainless steel to pretend to be 304 stainless steel to make tableware in order to reduce the cost of tableware manufacturing. Therefore, it is recommended that families buy stainless steel tableware through regular channels to buy guaranteed reputation or brand products, and buying tableware made of food-grade materials is healthier.


Now more and more tableware is made of stainless steel, and more and more people will use stainless steel tableware and kitchen utensils. It is not only convenient, but also lightweight and easy to clean, so these advantages make people like it even more. However, stainless steel tableware also has many series differences, some of which are not usable. So, the country allows 201 stainless steel tableware, is it illegal to make 201 stainless steel tableware?


The 200 series stainless steel has strong corrosion resistance, high alkali resistance and acid resistance. At the same time, it also has the characteristics of high density, polishing without bubbles, etc. It is very suitable for making various watch cases, strap bottom covers, etc. Quality material, however, the 200 series stainless steel series is not food grade stainless steel. Therefore, 201 stainless steel cannot be made into tableware.


In my country’s “Food Safety More Standard Stainless Steel Products” standard requirements, it means that any stainless steel can be made into tableware, but only after passing the test can a production license be obtained. The stainless steel products of the 200 series are not qualified to be made into tableware in China. Most of the time, they are mainly used as decorative materials. Because a large number of recycled stainless steel products are basically in this series, so 201 stainless steel is not in line with our country. It is illegal to make tableware according to food standards. So when you buy tableware, you can choose food grade 304 stainless steel series.

And for cookware, our CW52002-12N5 cookware set is made of 201 stainless steel, with the surface treatment with high quality polishing, which is so smooth and bright that people can see their face on it. For professional polishing it is a really important process; only enough smooth surface on pots or inside the pots brings stronger rust-resistance ability. This model with nice and smooth polishing means that it can last for so many years.
