12-inch flat-bottom wok. Triple-layer PFOA-free nonstick. Heavy-gauge, hard-anodized aluminum. Cast stainless steel loop handles. Dishwasher safe for easy cleanup. Oven safe to 450 degrees Fahrenheit. Drawing its inspiration from traditional woks, the Calphalon Contemporary Nonstick 12 in. Flat Bottom Wok features a flat bottom for easy stir-frying on electric or gas ranges. Yet its construction is truly modern, thanks to a triple-layer PFOA-free nonstick surface that's so tough it can be placed in the dishwasher. The heavy-gauge, hard-anodized aluminum promotes even heating, and the loop handles are made of cast stainless steel. Oven safe up to 450 degrees, this wok includes a manufacturer's lifetime warranty.
