 Stainless steel has good corrosion resistance, both durable and easy to clean, so many families will choose stainless steel tableware, cooking utensils, and other products. However, stainless steel products have great pressure on choice, use, and attention, as we will understand together.

Stainless steel products are selected, 304 steel is recommended. 304 steel (stainless steel containing 18% chromium and 8% nickel) is widely used in corrosion-resistant containers, tableware, furniture, railings, medical equipment and so on. Stainless steel products should be marked on the model when selecting stainless steel products. Stainless steel tableware has three codes: “13 # 0“ (420 steel), “18 # 0“ (430 steel) and “18 # 8“ (304 steel). The number at the front of the code represents the chromium content, and the number at the back of the code represents the nickel content. The safety of stainless steel utensils is mainly a problem of heavy metal migration. Generally speaking, 304 steel, which is common on the market, is a kind of steel with less chromium migration.

To use stainless steel products in a healthy manner, the following must be noted:

1. Salt, the acid composition should not be used for long-term use of Shengsheng stainless steel products. Stainless steel has good stability and corrosion resistance, but it does not mean it will not be corroded or rusted. If salt and vinegar are stored in stainless steel for a long time, it will cause the surface to rust or “taus eye“. Therefore, households are not recommended to use stainless steel products to store these items.

2. Don‘t fry Chinese herbs with stainless steel products. The composition of Chinese herbal medicine is complex, and most of them contain a variety of alkaloids and organic acids. When heated, it is easy to react with some components of stainless steel, which reduces the efficacy of drugs and may even produce more toxic substances.

3. Do not empty stainless steel products. Stainless steel products than iron, aluminum products, low thermal conductivity, thermal conductivity are relatively slow, empty will cause the surface of the cooker Chrome aging, fall off.

Finally, what should you pay attention to when cleaning stainless steel products? Stainless steel products have certain corrosion resistance, but in any case, after a long period of time may breed bacteria, or in a period of time for disinfection. When cleaning stainless steel products, do not use strong alkalinity and strong oxidants, such as alkaline water, soda ash, and bleaching powder, because these strong electrolytes and some components of the product will undergo “electrochemical reaction“, thus corroding stainless steel products. To get rid of harmful elements.
