This Professional Stainless Steel cookware Range comes with a 12 year warranty. They are made from Authenticate 202 stainless steel which is non magnetic and has a lower nickel content than 18/10. The nickel content has been replaced with manganese making them stronger and more durable than 18/10 stainless steel cookware. The bases are very thick and heavy because they are made from a three layer "sandwich" of stainless steel, aluminium & another layer of stainless steel. This allows for quick and even heat transference to the cooking surface of the pot. The pot handles are made from solid stainless steel rods which are welded onto stainless steel plates that are welded onto the sides of the smaller pots and and riveted onto the larger pots ensuring extra strength. The lids are recessed for a perfect fit Size: 160mm:D x 85mm:H - 1.7lt. Induction/Gas/Electric/Ceramic/Dishwasher safe.
