How to distinguish and ultrasonic vibration sieve shaker Material

       Used shaker customers know shaker sieve materials are stainless steel and ordinary steel two kinds , general steel shaker more economical , but now many of the materials

for equipment materials which have a screen machinery requirement for the stainless steel material contact parts material, stainless steel should be used and

Shaker, but stainless steel is also divided into 201,304,304 L, 316, 316L and other types or even better . So how customers distinguish shaker stainless steel used in the bad?

Here we tell you several ways .
The first method , magnetic experiment . Take a magnet vibrating sieve surface test to see with no magnetic force , if it is not a little suction, do not feel suction , it is

304 stainless steel , if you feel the suction is 201 stainless steel. However, this approach

201 and 304 can distinguish two kinds of screening equipment material, but can not distinguish between 304 and 316 types of stainless steel . In general most of the customers choice is 304 , and

this approach has been able to help customers distinguish whether the manufacturer of the plate with a 304 .
The second method , observation . 201 Stainless steel machining or ultrasonic vibration sieve shaker surface after polishing closer look will find some pitting, dark spots . The

304 stainless steel processing out of the sieve surface smooth and clean , bright brightness than 201 materials , 201

The brightness of the stainless steel material is slightly darker.
The third method , the chemical experiment . This approach requires the customer to use some chemicals to detect the composition of the stainless steel . However, this approach

is rarely used user .
Now used in many industries will generally require shaker 304 stainless steel , such as food, chemical, medical and other industries directly related to the safety of human life

. This material shaker acid than 201 materials , rust better.
