201 stainless steel plate because of its characteristics, so the frequency of application in industrial production is very high, many products are made of stainless steel plate using this type of model. How to distinguish 201 stainless steel plate? What is the method? In general, the quality of 201 stainless steel plate is not very good is very easy to cause wrinkles, is the surface of the stainless steel plate occurs in a variety of marks. Once these marks occur, they cannot be removed and will follow the entire production process of the raw material, even if the corresponding product is made, it will remain on the product. Therefore, this is the defect of the shoddy stainless steel plate. If the wrinkles occur, then the products made of such raw materials will become defective products immediately endanger the product honor production rate.

Method one, color observation

JiaNuo special steel tell you have work experience staff teacher can be based on the color of different models of stainless steel plate to distinguish the model of stainless steel plate. In general, the color of 201 stainless steel plate is more in-depth than the color of other models of stainless steel plate. This is due to the fact that this type of stainless steel plate also has a primary manganese, the storage of such primary elements can be a little darker stainless steel plate color. Although the color difference is not significant, but the work experience of the staff teacher is able to identify out according to the color.

Method two, scratch identification method

When the guys can not carry out according to the human eye to identify the different models of stainless steel plate, can carry out according to the scratch method to identify. Can find a more solid object must test the edge of the stainless steel plate scratch detection, if very casually will be scratched in the stainless steel plate surface to the marks, then basically can distinguish this model of stainless steel plate is 201 stainless steel plate. This is because this type of stainless steel plate with more carbon elements, resulting in the strength of this type of stainless steel plate is relatively low, so the surface is very easy to occur scratches. This is also often used to identify the way, although there is a certain damage to the stainless steel plate, this is a relatively fast method.

Method three, chemical changes to distinguish the way

As a technical professional stainless steel plate manufacturer Jianuo Special Steel are prepared in advance stainless steel detection chemicals. According to the chemical drops on the surface of the stainless steel plate, carefully observe the color change, it can be casually clear which raw material stainless steel plate. This is also a technical professional manufacturers often choose the way, according to this type of method is more accurate in comparison, can accurately distinguish the type of 201 stainless steel plate.

The surface of the cost effective 201 stainless steel plate is smooth and clean, and the surface of the stainless steel plate is not easy to have uneven air holes when you touch it by hand. The surface of the shoddy stainless steel plate will generally have many small round holes. Such small round holes are very harmful to the quality of the product, many products for the surface gloss has a very high regulation, there are small round holes in the stainless steel plate is unable to carry out the production process to make. Even if the production and processing into products, the product life will not be very high.
