How to buy stainless steel cookware?

Now the kitchen equipment industry is developing rapidly, stainless steel kitchenware with its excellent characteristics are loved by people, hotels, canteens, hospitals, etc. will buy stainless steel kitchenware for use. Today, kitchen equipment manufacturers will share with you how to buy stainless steel kitchenware.

First of all, choose a reliable stainless steel brand. Stainless steel kitchenware as the name suggests is made of stainless steel materials, the quality of stainless steel directly affects the quality of stainless steel kitchenware, therefore, to choose stainless steel kitchenware, you must choose a good stainless steel material. In our testing of stainless steel, we found that a very small amount of stainless steel tableware contains three serious toxic elements, lead, cadmium and arsenic, and these stainless steels may be derived from recycled scrap steel. The damage caused by these main chemical elements to the human body is mainly manifested in the following aspects: cadmium is mainly accumulated in organs such as kidneys and liver after absorption, and clinically manifested as proteinuria, amino aciduria, glycosuria, pain and pain; Mercury: organic mercury is very toxic, common Minamata disease methylmercury toxicity, inorganic mercury methylmercury can cause chronic central nervous system damage; Lead: Lead absorption is mainly in the duodenum, excreted through the kidneys and intestines to the hematopoietic system and nervous system and renal system is seriously damaged; Arsenic: Trivalent arsenic can cause substantial organ damage, skin diseases, and melanosis. Therefore, we must strictly choose reliable brands, and we must not trust stalls and unlicensed goods.

Secondly, the right type of stainless steel should be selected. Stainless steel can be divided into martensitic stainless steel, martensitic and semi-austenitic (or semi-martensitic) precipitation hardening stainless steel and martensitic aging stainless steel according to different structure and strengthening mechanism. Stainless steel is suitable for long-term contact with food, while martensitic type is not suitable due to its lack of corrosion resistance. Here is a simple way to distinguish austenite from martensite - that is, when choosing a pot, you can use a magnet to test the magnetism of the pot, if some or all of it is magnetic, it means that the pot is not austenitic stainless steel, then do not use.

Third, stainless steel kitchenware is not corrosion-resistant in all cases. In salt water, stainless steel can also be corroded, lose its bright appearance, and pose a safety hazard. Therefore, all stainless steel tableware should be cleaned with detergent after use and wiped dry; In order to prevent corrosion, stainless steel spoons and forks should not be soaked in the drink for a long time. Stainless steel containers should not be used to store food overnight (except dried fruits, etc.).
