It’s a good choice. It’s a martensitic stainless steel, so it’ll be hard, which makes for good polishing (the softer metals tend to tear and smear). Plus it also has limited carbides, which is what makes 440C so bad for polishing. The electroslag remelting makes for a clean steel, as well- very few inclusions.
