From Viking, this wok/chef's pan features:  For those who like cooking with cast iron but love the versatility of a clad stainless steel pan, the Viking Blue Carbon Steel 12-Inch Wok/Stir Fry Pan is the perfect pan. Featuring a 12-inch size for added versatility, this fry pan is made of carbon steel, an alloy that is a combination of iron and carbon. The “Blue” in “Blue carbon steel” references a heat treatment process to help resist rust and corrosion, a nuisance that can plague traditional cast iron pans. Stay-cool cast iron handles securely attach to the pans with heavy-duty rivets for confidence in construction and a lifetime of use. Though cast iron also excels at maintaining even heating, it can take time to rise to temperature and since iron itself is so brittle, more of the material must be used to make it durable, making traditional cast iron pans larger and heavier. With blue carbon steel, you’ll have a pan that is noticeably lighter without sacrificing performance. And like cast iron, blue carbon steel also heats quickly and evenly, reducing the risk of hot spots from occurring. Blue carbon steel is also prized for achieving high temperatures quickly without fear of damage occurring to the pan itself.   Includes 12" wok/stir fry pan Made without PTFE and PFOA Naturally nonstick due to the vegetable oil seasoning Pre-seasoned carbon steel construction for healthy, lightweight, and long-lasting cookware Blue carbon steel is lighter and more maneuverable than cast iron, making it easier for those who struggle with the weight of cast iron Features a matte finish and cut rims Cast iron handles Safe up to 600°F/315.556°C Compatible with all cooking surfaces; electric, gas, grill, induction, and oven friendly Hand wash only Limited lifetime warranty Imported.
