Release of stainless steel metal ions

Regarding the data on the precipitation of metal ions from 304 and 316L stainless steels, this is an experimental issue specific to certain conditions; the experimental results depend on many factors, including the degree of polishing, the measurement methods, and the operating conditions. Therefore, it is not possible to directly provide specific data differences in the precipitation of metal ions at different polishing degrees. Generally, the polishiness has a certain impact on the precipitation of metal ions. The higher the polish level of a surface, the lower its surface roughness is, and the smaller the area of the exposed metal surface. Consequently, the precipitation of metal ions also decreases. However, this is not absolute; other influencing factors such as temperature, pH, and redox conditions must also be considered. If you need to conduct this experiment, I suggest looking for papers in related fields or consulting professionals. Experiments must be carried out following strict procedures to ensure that all factors that could affect the results are properly controlled and taken into account. .

Generally, this kind of data is obtained from conditional experiments. This may require you or your organization to conduct immersion tests on these two types of stainless steels using your specific corrosive media, and then analyze the elements that have been corroded or dissolved. If data is available online, it is also limited to certain conditions.
