LIKE CAST IRON - BUT BETTER: Carbon steel frying pan from KitchenAid combines cast iron's culinary performance with lightweight, anti-rust convenience. RUST-RESISTANT: KitchenAid NITRO Carbon Steel cookware is made with innovative nitro heat technology to seal the surface of the pan and lock out the moisture that can cause rust. NITRO HARDENED: Nitrogen-infused skillet surface is 22 percent harder than traditional carbon steel for ultimate durability with a lighter weight. ALL RANGE COMPATIBLE: Carbon steel frying pan is induction suitable and oven/broiler safe up to 750°F. You can even use it on the grill. MAKE IT NONSTICK: Just like cast iron, carbon steel cookware can be seasoned over time to develop nonstick-like performance.
