With the development of science and technology, the quality of our buildings is more and more demanding.The quality of a building mainly depends on its structure and materials.The structure is designed by a special designer, and the materials are optional.Stainless steel is a modern application of more buildings, its kind and model is also very much.The most popular one is 304.
First of all, let us have a simple understanding of 304 stainless steel.
304 stainless steel, it is a versatile stainless steel material. The most outstanding thing is that it has good high temperature resistance and can reach a high temperature of 1200 degrees Celsius. Secondly, it has remarkable corrosion resistance, and its application fields are also very extensive, mainly in the field of food production and chemical engineering.
304 stainless steel is very popular, which will lead to counterfeit products on the market. After we briefly understand the basics of 304 stainless steel, let us know how to identify 304 stainless steel.
Method 1: With the help of professional professionals, professionals can distinguish the true and false of steel by the color and smoothness of the steel surface.
Method 2: Special steel inspection syrup, this syrup can be purchased in general hardware stores, so you don't have to worry about the source of supply. 304 stainless steel, it is not discolored within 3-5 minutes after the inspection of the syrup. In addition, 201 stainless steel, the potion will turn into dark brown red in a moment, 202 stainless steel, the potion will turn into light brown red in 5 seconds, 301 stainless steel, the potion will turn into a light brick red in 1-2 minutes.
Method 3: The magnetic properties of 304 stainless steel are relatively small, so we can buy a special magnet to distinguish the true and false of 304 stainless steel according to the size of the magnetic. If the magnetic is too large, it should be 202 stainless steel.
