What are the differences between 201 stainless steel, 304 stainless steel and 316 stainless steel?
2023-09-22
The corrosion resistance of 201 stainless steel is relatively poor, and the surface is dull, even if it is polished, it will appear black and bright. The corrosion resistance of 304 stainless steel will be higher than that of 201, the surface brightness is higher, and it is widely used. However, 316 stainless steel will add molybdenum element, which has better anti-corrosion and anti-rust performance.
In terms of usage, it is also different. 201 stainless steel are generally used on cheap products. 304 stainless steel is used in food industry, railings, and medical equipment. 316 stainless steel is commonly used in the pharmaceutical industry, aerospace, and shell surgical equipment. In addition, 316 stainless steel is better than 304 stainless steel, but the price is more expensive.
What should be paid attention to when using stainless steel materials？
In stainless steel materials, it is impossible to prevent foods such as salt, vinegar, and soy sauce for a long time. These foods contain electrolytes, which contribute to dissolve out.
Stainless steel containers cannot be used to cook traditional Chinese medicine. This is because there are many alkaloids and organic acids contained in traditional Chinese medicine. When heated in a stainless steel pot, a chemical reaction will occur, resulting in the loss of medicinal effect, and tin plating and other substances are prone to appear.
During the cleaning process of stainless steel containers, strong alkali or strong acid chemicals cannot be used for cleaning, otherwise chemical reactions will easily occur, resulting in corrosion of stainless steel. Moreover, it is not allowed to burn stainless steel pans empty, which will easily cause the chrome plating layer to fall off and age.
