Ok.

Steel-High quality=200m penetration, detonation activates on impact of armor. If the armor is strong enough, explosion will be directed to center of blast point to penetrate through more armor

Titanium-High quality=40m penetration, Explosion will be directed to center point of blast, resulting in a much better penetration value
