Standard for Electropolishing
Electropolishing of stainless steel alloys in the S2XXXX, S3XXXX and
S4XXXX series, and the precipitation hardened alloys is covered by British
Standard BS ISO 15730:2000.
The standard outlines the information to be supplied by the purchaser
if components are to be smoothed and passivated in accordance with ISO
15730.
Also covered are the test methods for testing the passivation of the
finished article.
Typically 5µm to 10µm of metal is removed from the surface
during electropolishing; however, up to 50µm may be removed for
additional smoothing. Greater amounts of metal will be removed from corners
and edges, i.e. areas of high current density unless shield and/or auxiliary
cathodes are used. |
