German designs have a helical rib on the penetrator which prevents it from buckling or snapping too easily

 

Not entirely sure whether this is a German design (seeing the Asian text), but it does show the helical rib:

The characters are of the Hangul alphabet i.e. Korean. This here looks like a K-276 APFSDS-T, made out of specially-treated tungsten to allow less deformation upon penetration.

Do you know what "special treatment" it got?

Well, "treatment" might not have been the correct term. More like "forging process".

From what I hear it's some sort of multi-stage heating process that helps reinforce the long rod's tungsten and diminish deformation during the self-sharpening phase. The same trick was apparently applied to the K-279. And that's about all I know on the matter. :-/

I had vaguely heard of this sort of thing being researched.  The idea was to alloy/treat tungsten in such a way that it behaves more like uranium on impact.
