Chemical Polishing for stainless steel (SST) / SUSpika (R)

Chemical Polishing for stainless steel (SST) / SUSpika (R)

We have developed “SUSpika” which is chemical polishing (CP) process for exclusive use of stainless steel with ULVAC, Inc.. SUSpika achieves good surface condition and vacuum property which is equal to EP treated surface, in addition, from a characteristic of CP, the treatment of complicated shape products is possible such as flexible tubes.

 
 
 

Description

Materials 304(L),316(L)
Standard polishing amount 5〜10 μm
Size Max 700 mm
 
 
 

Comparison with Electropolishing (EP)


  • SUSpika (304)

  • Electropolishing (304)

SUSpika treated surface is as well as EP treated surface !

Outgassing rate / unit area (304)


Outgassing rate is equal to EP treated
sample !

With vacuum baking,
outgassing rate 〜10-10 Pa・m・s-1!
 
 
 

Example

304 inner surface of flexible tube

After treatment, it is confirmed that the inner surface became glossy.
