How to select the safe tableware？Here are some suggestion for you.

As for kitchen supplies, stainless steel products are very common utensils and tools in our lives, many people will buy stainless steel tableware, because it is more practical and the price is relatively cheap. But it is also potentially dangerous if purchased inferior stainless steel, like inferior stainless steel bowls, off specification stainless steel chopsticks, substandard stainless steel pots, etc., which can destroy our bodies at any time, there  shows that how to buy stainless steel products is very significant.

A. Advantages of stainless steel tableware

There are many advantages of stainless steel tableware. Stainless steel tableware contains trace metal elements such as manganese, titanium, cobalt and molybdenum, which are indispensable trace elements of the human body. Since the human body cannot synthesize on its own, it must be ingested from the outside world. When the human body lacks one or more trace elements, it will suffer from a variety of diseases. The food cooked with stainless steel tableware, then people eat the food can make themselves obtain these trace elements and prevent the reaction with the acid and soda substances in the food, but also avoid the special iron smell after the rust of the general iron. Besides, it will not be broken with it is drop-resistant characteristic , which make it timeless using. Also, the surface is bright and beautiful and leaning is also worry-free.

2. Selection criteria 

Tableware always printed on the "13-0", "18-0", "18-8" three codes are made of stainless steel tableware, the number in front of the code indicates the amount of chromium, the number behind represents the nickel content, chromium is the material that makes the product not rust, and nickel is a corrosion-resistant material. For example, "13-0" contains 13% of chromium and does not contain nickel. Special attention should be paid to the following when purchasing: 

•  When purchasing stainless steel products, you should carefully check whether the material and steel number used are marked on the outer packaging; Whether to indicate the manufacturer's name, factory address, telephone, container hygiene standards and other words.

• You can judge it with a magnet. Regular manufacturers will generally use 304 ( 18-8) and 430 (18-0) stainless steel as fork spoons, 420 (that is, 13-0) as knives, 430 and 420 with magnetism, 304 is micromagnetic. 

•  In general, stainless steel tableware with the same thickness and shape, high-grade tableware will weigh more than low-grade tableware. However, the density difference is very small, 304 stainless steel is 7.93, and the density of 430 and 420 is 7.85, which is intuitively impossible to judge.

•  The stainless steel used for the production of tableware mainly includes "austenitic" stainless steel and "martensitic" stainless steel. Bowls, plates, etc. are generally produced by "austenitic" stainless steel, "austenitic" stainless steel has no magnetism; knives, forks, etc. are generally produced by "martensitic" stainless steel, and "martensite" stainless steel is magnetic. 

• Due to the different materials, the weight of qualified stainless steel tableware is greater than that of "parallel goods" products.
