With the improvement of the quality of life and the development of technology, we are becoming more and more strict with the quality of house construction, and the quality of the house depends on its decoration materials and structure, and stainless steel is the most used building material now. . Now let's take a look at how to distinguish true and false 304 stainless steel and what are the classification of stainless steel. How to identify the true and false of 304 stainless steel materials 1. Seek the help of professionals in this field when purchasing. They can easily distinguish the true and false of the steel only by the surface color of the steel and the smoothness of the touch. How to tell the true and false of 304 stainless steel 2. You can go to a hardware store to buy a potion that specializes in steel inspection. After 304 stainless steel has passed the potion test, it will not change color in 3 to 5 minutes. The 201 stainless steel material will instantly become dark brown or red when the medicine drops behind, and the 202 stainless steel material will change to light brown red within 5 to 10 seconds. How the veracity 3 304 stainless steel, 304 stainless steel because of its magnetic properties is not very large, it is possible to buy a magnet, and then to discriminate in accordance with the size of the magnetic, if the magnetic steel is relatively large, it is not true 304 stainless steel. What are the classifications of stainless steel: 1. Ferrite stainless steel This total stainless steel body contains 12% to 30% chromium, and their corrosion resistance, toughness and weldability increase with the increase of chromium content, and this type of steel can It is resistant to the corrosion of the atmosphere, nitric acid and saline solution, has good resistance to high temperature and oxidation, and is very suitable for nitric acid and food factory equipment. 2. Austenitic stainless steel In addition to containing about 18% of chromium, this stainless steel also contains about 8% of nickel and a small amount of other elements such as molybdenum, titanium, nitrogen, etc. The comprehensive performance is relatively good and can withstand the corrosion of various media. Most of them are used to make some acid-resistant equipment, such as equipment parts for corrosion-resistant containers or pipelines. 3. Martensitic stainless steel This stainless steel body has high strength, but poor plasticity and weldability. Its more commonly used models are 1Cr13 and 3Cr13. Because the carbon content is relatively high, it has high strength, hardness and wear resistance, but it is resistant. The corrosion resistance is worse than other steel bodies, and it is usually used for some mechanical properties such as springs and turbine blades, etc., and this type of steel body is used after quenching and tempering. Editor's summary: The above is all the content that the editor shared about how to distinguish true and false of 304 stainless steel and what are the classifications of stainless steel. Each type of stainless steel has different functions, and this kind of steel is everywhere in our lives. What, the decoration still uses his own money? !
