As the pace of life continues to accelerate, people's awareness of environmental protection has gradually increased, stainless steel cabinets have become the new favorite of home, how can high efficiency and choose high-quality stainless steel cabinets? What kinds of stainless steel, and how is it distinguished?
In the eyes of many consumers, there is almost no difference between 304 stainless steel and 201 stainless steel, which can hardly be distinguished, but they are different after all, the difference is as follows:
1, commonly used stainless steel plate is divided into 201# and 304# two models, the actual is the composition is different, 304# quality is better, but the price is expensive, 201# is worse.
2. The composition of 201# is 17Cr-4.5Ni-6Mn-N, which is a Ni steel type, which is magnetic after cold working and is used for railways and vehicles.
3, 304 # composition is 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel, used in food production equipment, chemical equipment, nuclear energy.
4, 201# is high in manganese, the surface is very bright with dark light, and the manganese is high and easy to rust. 304# contains more chromium, the surface is matte, no rust. The two are put together and there is comparison. The most important thing is that the corrosion resistance is different. The corrosion resistance of 201# is very poor, so the price is much cheaper. Because the 201# contains low nickel, the price is lower than 304#, so the corrosion resistance function is not as good as 304#. It’s gone.
5, the difference between 201# and 304# is the problem of nickel. And the price of 304# is now more expensive, but the 304# can at least guarantee that it will not rust during use. (Experiment with stainless steel potion)
6, stainless steel is not easy to rust because the formation of chromium-rich oxide on the surface of the steel can protect the steel body, 201 # material belongs to high manganese stainless steel than 304 # hardness, high carbon and low nickel.
7, the southern region, the rain is hot, humid, using 201# will rust, 304# is more practical; winter wind area, both are suitable, in the economic premise is not very sufficient to choose 201#, in the case of economic premise or It is recommended to use 304# in case of accident.
