At present, there are still many phenomena in which 304 is replaced by stainless steel 201. There is a common expectation by many consumers that it is almost no difference between 304 stainless steel and 201 stainless steel, which can hardly be distinguished by the naked eye. Therefore, Yaolong stainless steel light column manufacturer today teaches several methods to distinguish between 304 and 201.
Commonly used stainless steel plates are divided into two models, 201 and 304. Actually, the composition is different, and the 304 quality is better, but the price is expensive. 304 is imported stainless steel plate and 201 is domestic stainless steel plate.
2. the difference between molded steel:
The main component of the 201 stainless steel plate is 17Cr-4.5Ni-6Mn-N, which is Ni-shaped steel and is an alternative steel type for the 301 steel. After a certain period of cold working, 201 stainless steel plate obtained magnetic properties for railway vehicles. The 304 stainless steel plate is processed into 18Cr-9Ni, which is the most widely used stainless steel plate and a heat-resistant steel plate on the market. Generally used in food processing equipment, various chemical production equipment, nuclear power nuclear energy industry, outdoor lighting, such as the most widely used stainless steel light column.
3. The difference between manganese and nickel content:
stainless steel plate contains high manganese content, the surface of the steel plate is bright and has a dull light, but the high manganese content is more likely to rust. The 304 stainless steel plate has a high chromium content, and the surface of the steel plate is generally matte and less likely to rust. The most important aspect of the two steel plates is the difference in corrosion resistance. The overall corrosion resistance of 201 is low, it is easy to be corroded, and it is much cheaper in terms of price. Moreover, the nickel content of 201 is low, and the overall price is lower than that of 304 stainless steel plate. The biggest difference between the 201 stainless steel plate and the 304 stainless steel plate lies in the problem of nickel-containing elements. But the price of 304 is slightly more expensive, and the 304 stainless steel plate can at least keep rust in any use. Thus, when you purchase stainless steel light column, be sure to find a reliable supplier or use the option to check whether the stainless steel light column is 304 or 316. The drops on the 304 stainless steel light column have no color within 5 minutes, and the observation is invalid for more than 5 minutes. But the drops of water on the 201 stainless steel will immediately turn into a dark brown red;
It should be noted that this product is a chemical ingredient and has strong corrosiveness. It must be worn with gloves during the experiment. If you accidentally stick the clothes and the skin, rinse it with plenty of water immediately.
4. the difference of anti-rust rating:
The reason why the stainless steel plate is not easy to rust is that a kind of chromium-rich oxide is formed on the surface of the steel body during processing, thereby forming a protectable steel body, and the 201 steel material belongs to the high manganese steel and the hardness is high compared with 304. However,201 steel plate is easy to rust when it encounters water.
5. different composition:
(mainly from carbon, manganese, nickel, chromium containing several aspects to distinguish between 201 and 304 stainless steel)
201：C：≤0.15，Mn：5.50-7.50 P：≤0.060 S：≤1.00 Si：≤1.00 Cr：16.00-18.00 Ni：3.50-5.50 N：≤0.25
304：C：≤0.08，Mn：≤2.00 P：≤0.045 S：≤0.03 Si：≤1.00 Cr：18.00-20.00 Ni：8-10.50 N：≤0.10
