It's not Teflon, but it's probably some other kind of treatment for non-stick. The only non-treated stuff is stainless steel, aluminum, and cast iron. Aluminum is questionable and doesn't last long.
I worked for kitchenaid and I love their products. I don't know what the pan's coating is though. Again, I'm assuming it's another coating type.
For example from your link (stir fry pan):
Classic navy blue porcelain exterior
Nonstick interior is a patented hard-base ceramic nonstick system, a three coat process, that provides exceptional food release and durability
Thick aluminum core provides fast, even heating along the bottom of the pan
Handles are 18/10 stainless steel encased in soft silicone rubber
Tough porcelain enamel exterior is durable and easy to clean
Hand Wash Only
