When shopping for stainless steel cookware, try to avoid the 200 series. If you have a nickel allergy, you may need to avoid stainless steel entirely. In general, nickel leaches in higher amounts than the other metals. Through normal wear and tear, the metals in stainless steel will leach into food ( source).Ĭooking acidic foods will cause the pot to leach higher amounts. With less nickel, these pots are more vulnerable to corrosion they are also magnetic.Ģ00 series stainless steel is considered low quality and made with manganese instead of nickel ( source). With a higher amount of nickel, the 300 series is more resistant to corrosion and rust.Ī pot stamped 18/0 is part of the 400 series. The grade of stainless steel identifies how corrosive it is.ġ8/8 and 18/10 indicate that the pot is part of the 300 series of stainless steel. These numbers specifically refer to the amount of chromium and nickel blended into the stainless steel.įor example, the numbers 18/10 show that the pot is comprised of 18% chromium and 10% nickel. Those numbers you see on the bottom of your pot refer to the grade of stainless steel. What are those numbers on the bottom of your pots and pans? If your pot is rusting or if there are signs that the core is wearing through, it is time to replace the pot because it’s probably leaching those metals into your food. The aluminum or copper core becomes an issue ONLY if the pot is scratched, grooved, or worn to expose it. Stainless steel does not conduct heat well, so cookware is usually made with an aluminum or copper core: essentially, a sheet of aluminum or copper sandwiched between layers of stainless steel to improve the pot’s heating ability. The combination of metals determines the grade of the stainless steel. Other metals can include nickel, manganese, aluminum, silicon, and sulfur. It always contains at least 10% chromium. Stainless steel is a low carbon, iron-based steel with other metals mixed in to reduce corrosion and increase strength.
