The Distinction Method of Stainless Steel Vibrating Screens of Different Materials


1. Magnet identification
The 304 stainless steel commonly used in stainless steel vibrating screens will not have adsorption force when using a magnet, while the inferior 201 stainless steel magnet will have a slight adsorption force if it is near.
2. Identification of finish and brightness
After polishing the 304 stainless steel, the surface of the screen is smooth and tidy, while the inferior 201 stainless steel will have some pitting and dark spots on the surface of the vibrating screen after polishing.
3. Identification of chemical potions
Different materials of stainless steel can be quickly distinguished through chemical potions. Specific usage methods:
Put 1~2 drops of stainless steel identification liquid on the material to be tested, wait for a few seconds, the display effect: (such as stains on the surface of the stainless steel, and the coating must be cleaned before testing)
1) 201 stainless steel, the droplet instantly turns dark brown red;
2) 304 stainless steel, droplets do not change color within 3-5 minutes.
