Stainless steel kitchenware choose standard

- Apr 22, 2018-

  Stainless steel kitchen utensils are one of the indispensable kitchen utensils for household kitchen utensils. The stainless steel kitchen utensils on the market are mixed and the commodity price, anti-corrosion performance, and quality are also different. When selecting stainless steel kitchenware, there are the following major purchase criteria.

  Tableware is printed with "13-0", "18-0", "18-8" three kinds of code is the use of stainless steel cutlery, the code in front of the code indicates the amount of chromium, followed by the number of nickel content, chromium It is a material that does not rust the product, and nickel is a corrosion-resistant material. Such as "13-0" that contains 13% chromium, without nickel. When shopping, special attention should be paid to the following:

  1. When purchasing stainless steel products, you should carefully check whether the materials and steel numbers used on the outer packaging are marked; whether the manufacturer's name, address, telephone number, and container hygiene standard are indicated.

  2. It can be judged with a magnet. Regular manufacturers generally use 304 (ie, 18-8) and 430 (ie, 18-0) stainless steel fork spoons, 420 (ie, 13-0) knife, 430 and 420 are magnetic, and 304 is micromagnetic. However, the market has a tableware made of 201 and 202 materials, not on the magnetic, but whether it can be used to process tableware, the domestic is controversial. Some people think that 201, 202 materials containing high manganese, stainless steel does not belong to food grade.

  3. Under normal circumstances, the same thickness and shape of stainless steel cutlery, high-end cutlery will be heavier than the low-end material cutlery weight. However, the difference in density is very small. The density of stainless steel 304 is 7.93, and the density of 430 and 420 is 7.85, which cannot be judged by intuitiveness.

  4. It is best not to buy so-called stainless steel products in the hands of vendors. There are many kinds of stalls on the street. The boss often attracts consumers at a very low price. In fact, most of the stalls are fake, and the real stainless steel products are not so cheap. Because the price of the product is determined by the cost of the material being made, the kind of "stainless steel" that is floating is certainly not stainless steel that can be eaten. Therefore, the big guys must not try to buy the inferior products because they are unfair.
