I was about to say the same, although they are called "stainless", they are listed as having the same coating as the Platinum Chromes.I am getting deja vu by this, but according to BIC Greece, ASTOR is chrome and polymer coated too: https://gr.bicworld.com/sites/gr.bicworld.com/files/2019-02/BIC-Shavers-Greece-catalogue2017.pdf

Personally I had both great and terrible experiences with ASTOR, from tucks that were bought from different supermarkets.
I wonder if it is more to do with Greek manufacturing standards and quality control as opposed to them producing two different blades with blades being marketed outside of Greece (Chrome Platinum's) having to go through a higher level of quality control than the one's marketed within Greece?
