Stainless steel tableware generally contains chromium and nickel, chromium is the product does not rust the material, and nickel is corrosion-resistant materials. If the use of low-quality stainless steel tableware or improper use of stainless steel tableware, it is possible to cause heavy metals, chromium, cadmium and other human health hazards. You should pay attention to the parameters indicated in the purchase.
In stainless steel tableware often "13-0", "18-0", "18-8" Three kinds of code, Stainless Steel Cutlery the number in front of the code indicates the chromium content, the latter number represents the nickel content.
In general, the formal shopping malls sell brand-name products, regardless of quality performance, or from the health indicators should be no problem. However, stainless steel tableware if used improperly, the product's harmful metal elements will also accumulate in the human body slowly, when reached a certain limit, Stainless Steel Cutlery it will endanger human health. Stall, low price, "Three No" stainless steel tableware, preferably not to buy.
