Cybernox is the premium line from French commercial cookware manufacturer Sitram. With a stick-resistant surface that is 10x harder than steel, Cybernox features a lifetime warranty, even for commercial use. Sitram cookware has been used in fine European commercial kitchens for years. Cybernox, which means "quasi crystal," uses a stainless alloy originally developed for the nose cones of French rockets that can be heated to 1800 degrees Fahrenheit. This unique cookware is designed to be dishwasher safe, and you can clean it with your favourite scouring pad without damaging its surface. Its stick resistance won’t change over time - unlike other pans which may have excellent stick resistance when new, but deteriorate with time. You can use metal utensils on these pans (the surface is tougher than the utensils!). All Sitram products have NSF certification which indicates they are designed and warranted for restaurant/commercial use.
