Viking designed this saute pan with high walls to achieve remarkable cross-functionality, from searing to simmering, or browning to braising. The Viking Professional 6.4 qt. saute pan's 5-Ply construction makes this possible. It might be the only pan you ever need. The exterior layer is magnetic stainless steel that makes it suitable for induction stovetops. The next layer of aluminum alloy bonds to the middle layer, which is 3004 aluminum. The fourth layer is an aluminum alloy bonded to the interior 18/10 high-grade stainless steel. Together, these five layers work in unison to transfer heat quickly and evenly through the bottom and sides of the pan. The Viking-designed ergonomic handle takes stress off of the wrist, making cooking easier and enjoyable, while reducing heat transfer to keep the handle cool. The non-reactive and non-porous inner layer of stainless steel combines with the efficiency of the core to make an ideal cooking surface that is easy to clean and sanitize. The 5-ply construction is designed to be used in the oven the same way professional chefs use their cookware in a restaurant kitchen. Stove, oven, and grill friendly up to 600F degrees. HANDCRAFTED IN THE USA with a limited lifetime warranty.
